Modular Forms and Three Loop Superstring Amplitudes
We study a proposal of D’Hoker and Phong for the chiral superstring measure for genus three. A minor modification of the constraints they impose on certain Siegel modular forms leads to a unique solution. We reduce the problem of finding these modular forms, which depend on an even spin structure, to finding a modular form of weight 8 on a certain subgroup of the modular group. An explicit form...
متن کاملApplications of quadratic D-forms to generalized quadratic forms
In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.
متن کاملQuadratic APN functions as subspaces of alternating bilinear forms
In this note we illuminate and apply the equivalence of quadratic APN functions to certain subspaces of alternating bilinear forms. These subspaces can be characterized by the rank-distance of the dual subspace, or equivalently , as the subspaces of 2 F m 2 avoiding the variety of elements of rank 2. Or, in the geometric language, as subspaces external (or skew) to the line Grassmannian.
متن کاملRestrictions of SL3 Maass Forms to Maximal Flat Subspaces
We assume that ‖ψ‖2 = 1. We also assume that the spectral parameter of ψ is of the form tλ, where t> 1 and λ ∈ B∗, and B∗ is a fixed compact regular subset of a∗. Let Ω ⊆ X be a compact set. Let E ⊂Ω be a ball of radius 1 inside a maximal flat subspace of S. It was proved in [14, Theorem 1.2] that ‖ψ |E‖2 B∗,Ω t3/4, and moreover that this bound is sharp on the compact globally symmetric space S...
