On the integrality of the Taylor coefficients of mirror maps

We show that the Taylor coefficients of the series ${\bf q}(z)=z\exp({\bf G}(z)/{\bf F}(z))$ are integers, where ${\bf F}(z)$ and ${\bf G}(z)+\log(z) {\bf F}(z)$ are specific solutions of certain

Congruences between extremal modular forms and theta series of special types modulo powers of 2 and 3

Heninger, Rains and Sloane proved that the nth root of the theta series of any extremal even unimodular lattice in Rn has integer coefficients if n is of the form 2i3j5k(i ≥ 3). Motivated by their

The partition-frequency enumeration matrix

Abstract. We develop a calculus that gives an elementary approach to enumerate partition-like objects using an infinite upper-triangular number-theoretic matrix. We call this matrix the

On Rationally Parametrized Modular Equations

Many rationally parametrized elliptic modular equations are derived. Each comes from a family of elliptic curves attached to a genus-zero congruence subgroup $\Gamma_0(N)$, as an algebraic

We prove the integrality of the Taylor coefficients of roots of mirror maps at the origin. By mirror maps, we mean formal power series z.exp(G(z)/F(z)), where F(z) and G(z)+log(z)F(z) are particular

On Dwork's p-adic formal congruences theorem and hypergeometric mirror maps

Using Dwork's theory, we prove a broad generalisation of his famous p-adic formal congruences theorem. This enables us to prove certain p-adic congruences for the generalized hypergeometric series

Nonlinear differential equations satisfied by certain classical modular forms

A unified treatment is given of low-weight modular forms on Γ0(N), N = 2,3,4, that have Eisenstein series representations. For each N, certain weight-1 forms are shown to satisfy a coupled system of

Extremal Lattices

This paper deals with discrete subgroups of euclidean vector spaces, equivalently finitely generated free abelian groups (isomorphic to Z for some n ∈ N) together with a positive definite quadratic

On unique factorization domains

where u is a unit and p1, p2,. . . ,pk are primes in R. Note that the factorization is essentially unique (by the same argument used to prove uniqueness of factorization in PIDs). Note also that if R

THIS book must be welcomed most warmly into X the select class of Oxford books on pure mathematics which have reached a second edition. It obviously appeals to a large class of mathematical readers.

Extremal self-dual lattices exist only in dimensions 1 to 8

It is known that if A is a self-dual lattice in R", then min {u-u | u e A, u # 0} < (M/8) + 1. If equality holds the lattice is called extremal. In this paper we find all the extremal lattices: there

Self-Dual Codes over GF(4)

The Z4-linearity of Kerdock, Preparata, Goethals, and related codes

TLDR
Certain notorious nonlinear binary codes contain more codewords than any known linear code and can be very simply constructed as binary images under the Gray map of linear codes over Z/sub 4/, the integers mod 4 (although this requires a slight modification of the Preparata and Goethals codes).
