Computing Invariants of the Weil representation
Stephan Ehlen, Nils-Peter Skoruppa
We propose an algorithm for computing bases and dimensions of spaces of invariants of Weil representations of associated to finite quadratic modules. We…
Singular moduli of higher level and special cycles
Stephan Ehlen
We describe the complex multiplication (CM) values of modular functions for whose divisor is given by a linear combination of Heegner divisors in terms of special cycles o…
Vector valued theta functions associated with binary quadratic forms
Stephan Ehlen
We study the space of vector valued theta functions for the Weil representation of a positive definite even lattice of rank two with fundamental discriminant. We work out the relat…
On CM values of Borcherds products and harmonic weak Maass forms of weight one
Stephan Ehlen
We show that the values of Borcherds products on Shimura varieties of orthogonal type at certain CM points are given in terms of coefficients of the holomorphic part of weight one…
