  • Generalized Factorial Cumulants Applied to Coulomb-Blockade Systems Signal
    Generalized factorial cumulants applied to Coulomb-blockade systems signal time Von der Fakultät für Physik der Universität Duisburg-Essen genehmigte Dissertation zur Erlangung des Grades Dr. rer. nat. von Philipp Stegmann aus Bottrop Tag der Disputation: 05.07.2017 Referent: Prof. Dr. Jürgen König Korreferent: Prof. Dr. Christian Flindt Korreferent: Prof. Dr. Thomas Guhr Summary Tunneling of electrons through a Coulomb-blockade system is a stochastic (i.e., random) process. The number of the transferred electrons per time interval is determined by a prob- ability distribution. The form of this distribution can be characterized by quantities called cumulants. Recently developed electrometers allow for the observation of each electron transported through a Coulomb-blockade system in real time. Therefore, the probability distribution can be directly measured. In this thesis, we introduce generalized factorial cumulants as a new tool to analyze the information contained in the probability distribution. For any kind of Coulomb-blockade system, these cumulants can be used as follows: First, correlations between the tunneling electrons are proven by a certain sign of the cumulants. In the limit of short time intervals, additional criteria indicate correlations, respectively. The cumulants allow for the detection of correlations which cannot be noticed by commonly used quantities such as the current noise. We comment in detail on the necessary ingredients for the presence of correlations in the short-time limit and thereby explain recent experimental observations. Second, we introduce a mathematical procedure called inverse counting statistics. The procedure reconstructs, solely from a few experimentally measured cumulants, character- istic features of an otherwise unknown Coulomb-blockade system, e.g., a lower bound for the system dimension and the full spectrum of relaxation rates.

  • The Q-Factorial Moments of Discrete Q-Distributions and a Characterization of the Euler Distribution
    3 The q-Factorial Moments of Discrete q-Distributions and a Characterization of the Euler Distribution Ch. A. Charalambides and N. Papadatos Department of Mathematics, University of Athens, Athens, Greece ABSTRACT The classical discrete distributions binomial, geometric and negative binomial are defined on the stochastic model of a sequence of indepen- dent and identical Bernoulli trials. The Poisson distribution may be defined as an approximation of the binomial (or negative binomial) distribution. The cor- responding q-distributions are defined on the more general stochastic model of a sequence of Bernoulli trials with probability of success at any trial depending on the number of trials. In this paper targeting to the problem of calculating the moments of q-distributions, we introduce and study q-factorial moments, the calculation of which is as ease as the calculation of the factorial moments of the classical distributions. The usual factorial moments are connected with the q-factorial moments through the q-Stirling numbers of the first kind. Several ex- amples, illustrating the method, are presented. Further, the Euler distribution is characterized through its q-factorial moments. Keywords and phrases: q-distributions, q-moments, q-Stirling numbers 3.1 INTRODUCTION Consider a sequence of independent Bernoulli trials with probability of success at the ith trial pi, i =1, 2,.... The study of the distribution of the number Xn of successes up to the nth trial, as well as the closely related to it distribution of the number Yk of trials until the occurrence of the kth success, have attracted i−1 i−1 special attention.

  • 12. Probability Generating Functions for a Non-Negative Discrete Random
    PROBABILITY MODELS 47 12. Probability generating functions For a non-negative discrete random variable X, the probability generating function contains all possible information about X and is remarkably useful for easily deriving key properties about X. Definition 12.1 (Probability generating function). Let X 0 be a discrete random variable on 0; 1; 2;::: and let p := P X = k , k = 0; 1; 2;:::. The probability≥ generating function of X is f g k f g X X 1 k (21) GX(z):= Ez := z pk: k=0 For example, for X taking values 1 with probability 1=2, 2 with probability 1=3, and 3 with probability 1=6, we have 1 1 1 G (z) = z + z2 + z3: X 2 3 6 Paraphrasing Herb Wilf, we say that the probability generating function “hangs the distri- bution of X on a clothesline.” Notice that GX(1) = 1 and GX(0) = p0 for any random variable X. We summarize further properties of probability generating functions in the following theorem. Theorem 12.2 (Properties of generating functions). For non-negative discrete random variables X; Y 0, let GX and GY be their probability generating functions, respectively. Then ≥ a b (i) If Y = a + bX for scalars a; b R, then GY(z) = z GX(z ). 2 (ii) If X and Y are independent, then GX+Y(z) = GX(z)GY(z).

  • An Experimental Mathematics Approach to Several Combinatorial Problems
    AN EXPERIMENTAL MATHEMATICS APPROACH TO SEVERAL COMBINATORIAL PROBLEMS By YUKUN YAO A dissertation submitted to the School of Graduate Studies Rutgers, The State University of New Jersey In partial fulfillment of the requirements For the degree of Doctor of Philosophy Graduate Program in Mathematics Written under the direction of Doron Zeilberger And approved by New Brunswick, New Jersey May, 2020 ABSTRACT OF THE DISSERTATION An Experimental Mathematics Approach to Several Combinatorial Problems By YUKUN YAO Dissertation Director: Doron Zeilberger Experimental mathematics is an experimental approach to mathematics in which programming and symbolic computation are used to investigate mathematical objects, identify properties and patterns, discover facts and formulas and even automatically prove theorems. With an experimental mathematics approach, this dissertation deals with several combinatorial problems and demonstrates the methodology of experimental mathemat- ics. We start with parking functions and their moments of certain statistics. Then we discuss about spanning trees and \almost diagonal" matrices to illustrate the methodol- ogy of experimental mathematics. We also apply experimental mathematics to Quick- sort algorithms to study the running time. Finally we talk about the interesting peace- able queens problem. ii Acknowledgements First and foremost, I would like to thank my advisor, Doron Zeilberger, for all of his help, guidance and encouragement throughout my mathematical adventure in graduate school at Rutgers. He introduced me to the field of experimental mathematics and many interesting topics in combinatorics. Without him, this dissertation would not be possible. I am grateful to many professors at Rutgers: Michael Kiessling, for serving on my oral qualifying exam and thesis defense committee; Vladimir Retakh, for serving on my defense committee; Shubhangi Saraf and Swastik Kopparty, for teaching me combinatorics and serving on my oral exam committee.

Method of Moments Estimates for the Four-Parameter Beta Compound Binomial Model and the Calculation of Classification Consistency Indexes Bradley A. Hanson American College Testing September, 1991 I I Four-parameter Beta. Compound Binomial Abstract This paper presents a detailed derivation of method of moments estimates for the four- parameter beta compound binomial strong true score model. A procedure is presented to deal with the case in which the usual method of moments estimates do not exist or result in invalid parameter estimates. The results presented regarding the method of moments estimates are used to derive formulas for computing classification consistency indices under the four-paxameter beta compound binomial model. Acknowledgement. The author thanks Robert L. Brennan for carefully reading an earlier version of this paper and offering helpful suggestions and comments. Four-parameter Beta Compound Binomial The first part of this paper discusses estimation of the four-parameter beta compound binomial model by the method of moments. Most of the material in the first part of this paper is a restatement of material presented in Lord (1964, 1965) with some added details. The second part of this paper uses the results presented in the first part to obtain formulas for computing the classification consistency indexes described by Hanson and Brennan (1990).

Existing works consider that a user dynamically chooses the stations that cooperate for his/her service, but such assumption often has practical limitations. Instead, cooperation groups can be predefined and static, with nodes linked by fixed infrastructure. To analyze such a potential network, we propose a grouping method based on node proximity. With the Mutually Nearest Neighbour Relation, we allow the formation of singles and pairs of nodes.

    An umbral setting for cumulants and factorial moments E. Di Nardo, D. Senato ∗ Abstract We provide an algebraic setting for cumulants and factorial moments through the classical umbral calculus. Main tools are the compositional inverse of the unity umbra, connected with the logarithmic power series, and a new umbra here introduced, the singleton umbra. Various formulae are given expressing cumulants, factorial moments and central moments by umbral functions. Keywords: Umbral calculus, generating function, cumulant, factorial moment MSC-class: 05A40, 60C05 (Primary) 62A01(Secondary) 1 Introduction The purpose of this paper is mostly to show how the classical umbral calculus gives a lithe algebraic setting in handling cumulants and factorial moments. The classical umbral calculus consists of a symbolic technique dealing with sequences of numbers an indexed by nonnegative integers n = 0, 1, 2, 3,..., where the subscripts are treated as if they were powers. This kind of device was extensively used since the nineteenth century although the mathematical community was sceptic of it, owing to its lack of foundation. To the best of our knowledge, the method was first proposed by Rev. John Blissard in a series of papers as from 1861 (cf. [5] for the full list of papers), nevertheless it is impossible to put the credit of the original idea down to him since the Blissard’s calculus has its mathematical source in symbolic differentiation. In the thirties, Bell [1] reviewed the whole subject in several papers, restoring the purport of the Blissard’s idea and in [2] he tried to give a rigorous foundation of the arXiv:math/0412052v1 [math.PR] 2 Dec 2004 mystery at the ground of the umbral calculus but his attempt did not have a hold.

  • Raw and Central Moments of a Variety of Generalized Beta-Binomial Distributions Via Stirling Numbers
    "Science Stays True Here" Journal of Mathematics and Statistical Science, Volume 2016, 655-674 | Science Signpost Publishing Raw and Central Moments of a Variety of Generalized Beta-Binomial Distributions via Stirling Numbers Rachel Ogal School of Mathematics, CBPS College, University of Nairobi, P. O. Box 30197-00100, Nairobi, Kenya. Abstract In this article, we consider the construction of various compound Binomials by mixing the success parameter with generalized Beta distributions within the unit interval. We then proceed to calculate the moments of the derived mixtures using Stirling numbers of the second kind. Keywords: Binomial mixtures, Central moments, Factorial moments, Generalized Beta distributions, Raw moments, Stirling numbers. 1. Introduction If we let a random variable X to represent the total number of successes in n Bernoulli experiments, then X is said to be Binomially distributed and has parameters n and ϑ . ϑ denotes the probability of success hence lies within the unit interval, 01<<ϑ , and can be taken to be a continuous random variable with density g()ϑ . This formulates the density fx() referred to as a Binomial mixture. 1 n x nx− fx()=∫ ϑ( 1 − ϑ) g () ϑϑ d (1) 0 x The Beta distribution offers a tractable prior to the Binomial, and has been used in this sense (see, for instance, Skellam (1948); Ishii and Hayakawa (1960); Chatfield and Goodhardt (1970)). Various generalizations of the Beta distribution have also been developed and used as priors to the Binomial (see, for instance, Gerstenkorn (2004); Rodriguez-Avi et al. (2007)). 656 Raw and Central Moments of a Variety of Generalized Beta-Binomial Distributions via Stirling Numbers We aim to construct Binomial mixtures whose priors are generalizations of the Beta, and derive some of their properties using stirling numbers of the second kind.

This chapter sets out the mathematical theory of such processes. After some motivation, several ways to characterize the distribution of a point process are described in Section 16.1.2. The important notions of Campbell and moment measures are introduced
