    A MATHEMATICIAN’S SURVIVAL GUIDE PETER G. CASAZZA 1. An Algebra Teacher I could Understand Emmy award-winning journalist and bestselling author Cokie Roberts once said: As long as algebra is taught in school, there will be prayer in school. 1.1. An Object of Pride. Mathematician’s relationship with the general public most closely resembles “bipolar” disorder - at the same time they admire us and hate us. Almost everyone has had at least one bad experience with mathematics during some part of their education. Get into any taxi and tell the driver you are a mathematician and the response is predictable. First, there is silence while the driver relives his greatest nightmare - taking algebra. Next, you will hear the immortal words: “I was never any good at mathematics.” My response is: “I was never any good at being a taxi driver so I went into mathematics.” You can learn a lot from taxi drivers if you just don’t tell them you are a mathematician. Why get started on the wrong foot? The mathematician David Mumford put it: “I am accustomed, as a professional mathematician, to living in a sort of vacuum, surrounded by people who declare with an odd sort of pride that they are mathematically illiterate.” 1.2. A Balancing Act. The other most common response we get from the public is: “I can’t even balance my checkbook.” This reflects the fact that the public thinks that mathematics is basically just adding numbers. They have no idea what we really do. Because of the textbooks they studied, they think that all needed mathematics has already been discovered.

  • PRESENTAZIONE E LAUDATIO DI DAVID MUMFOD by ALBERTO
    PRESENTAZIONE E LAUDATIO DI DAVID MUMFOD by ALBERTO CONTE David Mumford was born in 1937 in Worth (West Sussex, UK) in an old English farm house. His father, William Mumford, was British, ... a visionary with an international perspective, who started an experimental school in Tanzania based on the idea of appropriate technology... Mumford's father worked for the United Nations from its foundations in 1945 and this was his job while Mumford was growing up. Mumford's mother was American and the family lived on Long Island Sound in the United States, a semi-enclosed arm of the North Atlantic Ocean with the New York- Connecticut shore on the north and Long Island to the south. After attending Exeter School, Mumford entered Harvard University. After graduating from Harvard, Mumford was appointed to the staff there. He was appointed professor of mathematics in 1967 and, ten years later, he became Higgins Professor. He was chairman of the Mathematics Department at Harvard from 1981 to 1984 and MacArthur Fellow from 1987 to 1992. In 1996 Mumford moved to the Division of Applied Mathematics of Brown University where he is now Professor Emeritus. Mumford has received many honours for his scientific work. First of all, the Fields Medal (1974), the highest distinction for a mathematician. He was awarded the Shaw Prize in 2006, the Steele Prize for Mathematical Exposition by the American Mathematical Society in 2007, and the Wolf Prize in 2008. Upon receiving this award from the hands of Israeli President Shimon Peres he announced that he will donate the money to Bir Zeit University, near Ramallah, and to Gisha, an Israeli organization that advocates for Palestinian freedom of movement, by saying: I decided to donate my share of the Wolf Prize to enable the academic community in occupied Palestine to survive and thrive.

  • Density of Algebraic Points on Noetherian Varieties 3
    DENSITY OF ALGEBRAIC POINTS ON NOETHERIAN VARIETIES GAL BINYAMINI Abstract. Let Ω ⊂ Rn be a relatively compact domain. A finite collection of real-valued functions on Ω is called a Noetherian chain if the partial derivatives of each function are expressible as polynomials in the functions. A Noether- ian function is a polynomial combination of elements of a Noetherian chain. We introduce Noetherian parameters (degrees, size of the coefficients) which measure the complexity of a Noetherian chain. Our main result is an explicit form of the Pila-Wilkie theorem for sets defined using Noetherian equalities and inequalities: for any ε> 0, the number of points of height H in the tran- scendental part of the set is at most C ·Hε where C can be explicitly estimated from the Noetherian parameters and ε. We show that many functions of interest in arithmetic geometry fall within the Noetherian class, including elliptic and abelian functions, modular func- tions and universal covers of compact Riemann surfaces, Jacobi theta func- tions, periods of algebraic integrals, and the uniformizing map of the Siegel modular variety Ag . We thus effectivize the (geometric side of) Pila-Zannier strategy for unlikely intersections in those instances that involve only compact domains. 1. Introduction 1.1. The (real) Noetherian class. Let ΩR ⊂ Rn be a bounded domain, and n denote by x := (x1,...,xn) a system of coordinates on R . A collection of analytic ℓ functions φ := (φ1,...,φℓ): Ω¯ R → R is called a (complex) real Noetherian chain if it satisfies an overdetermined system of algebraic partial differential equations, i =1,...,ℓ ∂φi = Pi,j (x, φ), (1) ∂xj j =1,...,n where P are polynomials.

  • On the Strong Density Conjecture for Integral Apollonian Circle Packings
    ON THE STRONG DENSITY CONJECTURE FOR INTEGRAL APOLLONIAN CIRCLE PACKINGS JEAN BOURGAIN AND ALEX KONTOROVICH Abstract. We prove that a set of density one satisfies the Strong Density Conjecture for Apollonian Circle Packings. That is, for a fixed integral, primitive Apollonian gasket, almost every (in the sense of density) sufficiently large, admissible (passing local ob- structions) integer is the curvature of some circle in the packing.

Section 4.1 for the statement of the conjecture). This is done in Chapter 4, where further discussion of the conjecture and past work can be found. To give our construction, we must first develop the theory of pinchings a la Ferrand [8] in flat families and understand the behavior of the relative Picard functor for such pinchings, and this is the contents of Chapter 3. In Chapter 2 we recall some of the results and definitions we will need from algebraic geometry; the reader already familiar with these results should have no problem beginning with Chapter 3 and referring back only for references and to fix definitions.

  • Asymptotic Sieve for Primes 1043
    Annals of Mathematics, 148 (1998), 1041–1065 Asymptotic sieve for primes By John Friedlander and Henryk Iwaniec 1. Heuristics and statement of results For a long time it was believed that sieve methods might be incapable of achieving the goal for which they had been created, the detection of prime numbers. Indeed, it was shown [S], [B] to be inevitable that, in the sieve’s original framework, no such result was possible although one could come tan- talizingly close. This general limitation is recognized as the “parity problem” of sieve theory. More recently, beginning with the work [IJ], this goal has in certain cases become possible by adapting the sieve machinery to enable it to take advantage of the input of additional analytic data. There have been a number of recent developments in this regard, for example [H], [DFI], [FI], and several recent works of R.C. Baker and G. Harman. The story however is far from finished. In this paper we consider a sequence of real nonnegative numbers (1.1) = (a ) A n with the purpose of showing an asymptotic formula for (1.2) S(x)= anΛ(n) nX6x where Λ(n) denotes the von Mangoldt function. The sequence can be quite A thin although not arbitrarily so. Setting arXiv:math/9811186v1 [math.NT] 1 Nov 1998 (1.3) A(x)= an nX6x we require that A(x) be slightly larger than A(√x); precisely (1.4) A(x) A(√x)(log x)2 . ≫ *JF was supported in part by NSERC grant A5123 and HI was supported in part by NSF grant DMS-9500797.
