چکیده

More than forty years ago, Igusa proved in [Ig] a “Fundamental Lemma”, according to which, theta constants give an explicit generically injective map from some modular varieties related to the symplectic group Sp(n, R) into the projective space. The embedded varieties satisfy some quartic relations, the so called Riemann’s relations. We expect that similar results hold for orthogonal instead of symplectic groups, where one should use typical “orthogonal constructions” instead of theta series.

Upper Bounds for Modular Forms, Lattices, and Codes

Let W(z) = 1 + Ad ezmidr + AdCl ewrim+lM +. .. be a modular form of weight n for the full modular group. real part. This implies that there is no even unimodular lattice in E " , for n > n, , having minimum nonzero squared length > n/12-b. A similar argument shows that there is no binary self-dual code of length n > n, having all weights divisible by 4 and minimum nonzero weight > n/6-6. A corr...

We study the SU(2) Witten–Reshetikhin–Turaev invariant for the Seifert fibered homology spheres with M-exceptional fibers. We show that the WRT invariant can be written in terms of (differential of) the Eichler integrals of modular forms with weight 1/2 and 3/2. By use of nearly modular property of the Eichler integrals we shall obtain asymptotic expansions of the WRT invariant in the large-N l...

Golden lattices

A golden lattice is an even unimodular Z[ 1+ √ 5 2 ]-lattice of which the Hilbert theta series is an extremal Hilbert modular form. We construct golden lattices from extremal even unimodular lattices and obtain families of dense modular lattices.

We give a geometric construct of a modular functor for any simple Lie-algebra and any level by twisting the constructions in [16] and [19] by a certain fractional power of the abelian theory first considered in [13] and further studied in [2].
