Singular moduli of higher level and special cycles

Stephan Ehlen

We describe the complex multiplication (CM) values of modular functions for $Γ_{0} (N)$ 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…
