A Concise History of Mathematics the Beginnings 3
A CONCISE HISTORY OF A CONCISE HISTORY MATHEMATICS STRUIK OF MATHEMATICS DIRK J. STRUIK Professor Mathematics, BELL of Massachussetts Institute of Technology i Professor Struik has achieved the seemingly impossible task of compress- ing the history of mathematics into less than three hundred pages. By stressing the unfolding of a few main ideas and by minimizing references to other develop- ments, the author has been able to fol- low Egyptian, Babylonian, Chinese, Indian, Greek, Arabian, and Western mathematics from the earliest records to the beginning of the present century. He has based his account of nineteenth cen- tury advances on persons and schools rather than on subjects as the treatment by subjects has already been used in existing books. Important mathema- ticians whose work is analysed in detail are Euclid, Archimedes, Diophantos, Hammurabi, Bernoulli, Fermat, Euler, Newton, Leibniz, Laplace, Lagrange, Gauss, Jacobi, Riemann, Cremona, Betti, and others. Among the 47 illustra- tions arc portraits of many of these great figures. Each chapter is followed by a select bibliography. CHARLES WILSON A CONCISE HISTORY OF MATHEMATICS by DIRK. J.

The Rectification of Quadratures As a Central Foundational Problem for The
Historia Mathematica 39 (2012) 405–431 www.elsevier.com/locate/yhmat The rectification of quadratures as a central foundational problem for the early Leibnizian calculus Viktor Blåsjö Utrecht University, Postbus 80.010, 3508 TA Utrecht, The Netherlands Available online 2 August 2012 Abstract Transcendental curves posed a foundational challenge for the early calculus, as they demanded an extension of traditional notions of geometrical rigour and method. One of the main early responses to this challenge was to strive for the reduction of quadratures to rectifications. I analyse the arguments given to justify this enterprise and propose a hypothesis as to their underlying rationale. I then go on to argue that these foundational con- cerns provided the true motivation for much ostensibly applied work in this period, using Leibniz’s envelope paper of 1694 as a case study.

Zusammenfassung Transzendentale Kurven stellten eine grundlegende Herausforderung für die frühen Infinitesimalkalkül dar, da sie eine Erweiterung der traditionellen Vorstellungen von geometrischen Strenge und Verfahren gefordert haben. Eines der wichtigsten frühen Antworten auf diese Herausforderung war ein Streben nach die Reduktion von Quadraturen zu Rektifikationen. Ich analysiere die Argumente die dieses Unternehmen gerechtfertigt haben und schlage eine Hypothese im Hinblick auf ihre grundlegenden Prinzipien vor. Ich behaupte weiter, dass diese grundlegenden Fragenkomplexe die wahre Motivation für viel scheinbar angewandte Arbeit in dieser Zeit waren, und benutze dafür Leibniz’ Enveloppeartikel von 1694 als Fallstudie.

COUNTING RATIONAL POINTS AND LOWER BOUNDS FOR GALOIS ORBITS HARRY SCHMIDT Abstract. In this article we present a new method to obtain polynomial lower bounds for Galois orbits of torsion points of one dimensional group varieties. 1. Introduction In this article we introduce a method that allows in certain situations to obtain lower bounds for the degree of number fields associated to a sequence of polynomial equations. By a Galois bound for such a sequence we mean a lower bound for the degree of these number fields that is polynomial in the degree of the polynomials. Maybe the simplest example is Xn = 1 where n runs through the positive integers. For a primitive solution ζn of this equation, that is, one that does not show up for smaller n this is just the well-known Galois bound 1−ǫ for roots of unity [Q(ζn) : Q] ǫ n . The Galois bound here was proven by Gauss. Another example are the equations≫ Bn(X) = 0 where Bn is the division polynomial. For a fixed elliptic curve E given in Weiertrass form E : Y 2 = 4X3 g X g − 2 − 3 this is defined by [n](X,Y ) = An(X) ,y where A Q(g , g )[X] is a monic poly- Bn(X) n n ∈ 2 3 2 2 nomial of degree n and Bn Q(g2, g3)[X] is of degree n 1 with leading coefficient n2 [Sil92, p.105, Exercise 3.7].∈ Here Galois bounds are not− known as long as for roots of unity. The only known methods to obtain Galois bounds so far seem to be either through Serre’s open image theorem [Lom15, Corollary 9.5] (in the non CM case), class field theory[GR18, Th´eor`eme 2], [Sil88, (1.1)](in the CM case), or (in both cases) tran- scendence techniques as for instance applied by Masser [Mas89] and further developed arXiv:1802.02192v3 [math.NT] 20 Feb 2019 by David [Dav97]. -

INTEGER POINTS CLOSE TO A TRANSCENDENTAL CURVE AND CORRECTLY-ROUNDED EVALUATION OF A FUNCTION NICOLAS BRISEBARRE AND GUILLAUME HANROT Abstract. Despite several significant advances over the last 30 years, guar- anteeing the correctly rounded evaluation of elementary functions, such as √ cos, exp, 3 · for instance, is still a difficult issue. This can be formulated asa Diophantine approximation problem, called the Table Maker’s Dilemma, which consists in determining points with integer coordinates that are close to a curve. In this article, we propose two algorithmic approaches to tackle this problem, closely related to a celebrated work by Bombieri and Pila and to the so-called Coppersmith’s method. We establish the underlying theoretical foundations, prove the algorithms, study their complexity and present practical experiments; we also compare our approach with previously existing ones. -
Bundle Block Adjustment with 3D Natural Cubic Splines
BUNDLE BLOCK ADJUSTMENT WITH 3D NATURAL CUBIC SPLINES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Won Hee Lee, B.S., M.S. ***** The Ohio State University 2008 Dissertation Committee: Approved by Prof. Anton F. Schenk, Adviser Prof. Alper Yilmaz, Co-Adviser Adviser Prof. Ralph von Frese Graduate Program in Geodetic Science & Surveying c Copyright by Won Hee Lee 2008 ABSTRACT One of the major tasks in digital photogrammetry is to determine the orienta- tion parameters of aerial imageries correctly and quickly, which involves two primary steps of interior orientation and exterior orientation. Interior orientation defines a transformation to a 3D image coordinate system with respect to the camera’s per- spective center, while a pixel coordinate system is the reference system for a digital image, using the geometric relationship between the photo coordinate system and the instrument coordinate system. While the aerial photography provides the interior orientation parameters, the problem is reduced to determine the exterior orientation with respect to the object coordinate system. Exterior orientation establishes the position of the camera projection center in the ground coordinate system and three rotation angles of the camera axis to represent the transformation between the image and the object coordinate system. Exterior orientation parameters (EOPs) of the stereo model consisting of two aerial imageries can be obtained using relative and absolute orientation. EOPs of multiple overlapping aerial imageries can be computed using bundle block adjustment. Bundle block adjustment reduces the cost of field surveying in difficult areas and verifies the accuracy of field surveying during the process of bundle block adjustment. -
Points of Bounded Height on Oscillatory Sets
POINTS OF BOUNDED HEIGHT ON OSCILLATORY SETS GEORGES COMTE AND CHRIS MILLER Abstract. We show that transcendental curves in Rn (not necessarily compact) have few rational points of bounded height provided that the curves are well behaved with respect to algebraic sets in a certain sense and can be parametrized by functions belonging to a specified algebra of infinitely differentiable functions. Examples of such curves include logarithmic spirals and solutions to Euler equations x2y′′ +xy′ + cy =0 with c> 0. 1. Introduction n The height of (a1/b1,...,an/bn) Q is by definition max ai , bi : i =1, , n , 2 ∈ n {| | | | ··· } when each pair (ai, bi) Z is coprime. For X R and T 0, let #X(Q, T ) be the number of points in X∈ Qn of height at most ⊆T . ≥ The overarching question:∩ What is the asymptotic behaviour of #X(Q, T ) as T + ? As it can be notoriously difficult to determine whether X has any rational→ points∞ at all, emphasis tends to be on the establishment of upper bounds. We say that #X(Q, T ) is sub-polynomial if log(max 1, #X(Q, T ) ) lim { } =0. T →+∞ log T For temporary convenience in exposition, we put log(max 1, #X(Q, T ) ) ρ(X)= lim { } [0, + ], T →+∞ log log T ∈ ∞ and say that X has finite order if ρ(X) < . There is a natural split between the algebraic∞ and the transcendental; we are con- cerned with the latter. Indeed, if X is algebraic, then #X(Q, T ) is usually not arXiv:1601.03033v3 [math.AG] 16 Apr 2017 sub-polynomial (see for instance Browning, Heath-Brown and Salberger [9]).
