Linear Algebraic Groups Calendar This Calendar lists all of the meetings which have been approved by the Council up to the date this issue of the c/{oticeiJ was sent to press. The summer and annual meetings are joint meetings of the Mathematical Association of America and the American Mathematical Society. The meeting dates which fall rather far in the future are subject to change; this is particularly true of meetings to which no numbers have yet been assigned. Abstracts should be submitted on special forms which are available in most departments of mathematics; forms can also be obtained by writing to the headquarters of the Society. Abstracts to be presented at the meeting in person must be received at the headquarters of the Society in Providence, Rhode Island, on or before the deadline for the meeting.

  • Classifying Regular Languages Via Cascade Products of Automata
    Classifying Regular Languages via Cascade Products of Automata Marcus Gelderie RWTH Aachen, Lehrstuhl f¨urInformatik 7, D-52056 Aachen [email protected] Abstract. Building on the celebrated Krohn-Rhodes Theorem we char- acterize classes of regular languages in terms of the cascade decomposi- tions of minimal DFA of languages in those classes. More precisely we provide characterizations for the classes of piecewise testable languages and commutative languages. To this end we use biased resets, which are resets in the classical sense, that can change their state at most once. Next, we introduce the concept of the scope of a cascade product of reset automata in order to capture a notion of locality inside a cascade prod- uct and show that there exist constant bounds on the scope for certain classes of languages. Finally we investigate the impact of biased resets in a product of resets on the dot-depth of languages recognized by this product. This investigation allows us to refine an upper bound on the dot-depth of a language, given by Cohen and Brzozowski. 1 Introduction A significant result in the structure theory of regular languages is the Krohn- Rhodes Theorem [7], which states that any finite automaton can be decomposed into simple \prime factors" (a detailed exposition is given in [4, 6, 9, 10]). We use the Krohn-Rhodes Theorem to characterize classes of regular lan- guages in terms of the decompositions of the corresponding minimal automata. In [8] this has been done for star-free languages by giving an alternative proof for the famous Sch¨utzenberger Theorem [11].

  • Spacecraft Trajectories in a Sun, Earth, and Moon Ephemeris Model
    SPACECRAFT TRAJECTORIES IN A SUN, EARTH, AND MOON EPHEMERIS MODEL A Project Presented to The Faculty of the Department of Aerospace Engineering San José State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Aerospace Engineering by Romalyn Mirador i ABSTRACT SPACECRAFT TRAJECTORIES IN A SUN, EARTH, AND MOON EPHEMERIS MODEL by Romalyn Mirador This project details the process of building, testing, and comparing a tool to simulate spacecraft trajectories using an ephemeris N-Body model. Different trajectory models and methods of solving are reviewed. Using the Ephemeris positions of the Earth, Moon and Sun, a code for higher-fidelity numerical modeling is built and tested using MATLAB. Resulting trajectories are compared to NASA’s GMAT for accuracy. Results reveal that the N-Body model can be used to find complex trajectories but would need to include other perturbations like gravity harmonics to model more accurate trajectories. i ACKNOWLEDGEMENTS I would like to thank my family and friends for their continuous encouragement and support throughout all these years. A special thank you to my advisor, Dr. Capdevila, and my friend, Dhathri, for mentoring me as I work on this project. The knowledge and guidance from the both of you has helped me tremendously and I appreciate everything you both have done to help me get here. ii Table of Contents List of Symbols ............................................................................................................................... v 1.0 INTRODUCTION

As originally intended, this handbook is designed to serve as a reference manual for policy makers, program managers, educators, engineers, and scientists alike. It contains information for the uninitiated, providing insight into the fundamental behavior of tethers in space. For those familiar with space tethers, it summarizes past and ongoing studies and programs, a complete bibliography of tether publications, and names, addresses, and phone numbers of workers in the field. Perhaps its most valuable asset is the brief description of nearly 50 tether applications which have been proposed and analyzed over the past 10 years.

Recently, 2 the quantum versions of classical games, such as the Prisoner’s Dilemma (PD), have attracted a lot of 3 attention. Similarly, state machines and specifically finite automata have also been under constant 4 and thorough study for plenty of reasons. The quantum analogues of these abstract machines, like the 5 quantum finite automata, have been studied extensively. In this work, we examine some well-known 6 game conditional strategies that have been studied within the framework of the repeated PD game. 7 Then, we try to associate these strategies to proper quantum finite automata that receive them as 8 inputs and recognize them with probability 1, achieving some interesting results. We also study the 9 quantum version of PD under the Eisert-Wilkens-Lewenstein scheme, proposing a novel conditional 10 strategy for the repeated version of this game. 11 Keywords: quantum game theory, quantum automata, prisoner’s dilemma, conditional strategies, 12 quantum strategies 13 1. Introduction 14 Quantum game theory has gained a lot of research interest since the first pioneering works of the 15 late ’90s [1–5].

Brown provided an unusually congenial and stimulating environment for my teaching and research. I never regretted our decision in 1958 to accept an Assistant Professorship in the Mathematics Department, nor did I ever pursue seriously opportunities to move from Brown to another university in the years afterward. For convenience, these remembrances of my first 20 years at Brown are divided into several parts. Part I concerns the years from 1958-68 and Part II from 1968-1978. Part III concerns my research contributions during those 20 years. A brief Afterword mentions my later years at Brown and the years of retirement.

    New Congruences and Finite Difference Equations for Generalized Factorial Functions Maxie D. Schmidt University of Washington Department of Mathematics Padelford Hall Seattle, WA 98195 USA [email protected] Abstract th We use the rationality of the generalized h convergent functions, Convh(α, R; z), to the infinite J-fraction expansions enumerating the generalized factorial product se- quences, pn(α, R)= R(R + α) · · · (R + (n − 1)α), defined in the references to construct new congruences and h-order finite difference equations for generalized factorial func- tions modulo hαt for any primes or odd integers h ≥ 2 and integers 0 ≤ t ≤ h. Special cases of the results we consider within the article include applications to new congru- ences and exact formulas for the α-factorial functions, n!(α). Applications of the new results we consider within the article include new finite sums for the α-factorial func- tions, restatements of classical necessary and sufficient conditions of the primality of special integer subsequences and tuples, and new finite sums for the single and double factorial functions modulo integers h ≥ 2. 1 Notation and other conventions in the article 1.1 Notation and special sequences arXiv:1701.04741v1 [math.CO] 17 Jan 2017 Most of the conventions in the article are consistent with the notation employed within the Concrete Mathematics reference, and the conventions defined in the introduction to the first articles [11, 12]. These conventions include the following particular notational variants: ◮ Extraction of formal power series coefficients. The special notation for formal n k power series coefficient extraction, [z ] k fkz :7→ fn; ◮ Iverson’s convention.
