Abstract:

In this paper, we study the zeros of $L$-functions attached to cusp forms of half-integral weight. Firstly, we find an explicit vertical strip in the complex plane in which all the non-trivial zeros of the $L$-function attached to a cusp form of half-integral weight lie. Secondly, we prove that the $L$-function attached to certain cusp forms of half-integral weight have infinitely many zeros of odd order on the critical line.
