Abstract: 

The theta series of a positive definite quadratic lattice is a modular form. The geometric theta series of a hermitian lattice with sign (n-1,1) is a generating series of special divisors on unitary Shimura varieties, which is also modular. In this talk, I will give a review on the story and present results on the modularity of arithmetic theta series with parahoric levels.
