Linear independence of theta series of positive-definite, unimodular even lattices
Manuel K. -H. Müller
We show that the minimal for which the degree theta series of positive-definite, unimodular even lattices of rank are linearly independent is bounded between $\fr…

The basis problem for modular forms for the Weil representation
Manuel K. -H. Müller
The vector valued theta series of a positive-definite even lattice is a modular form for the Weil representation of . We show that the space of cusp form…
