Th. Yang, EIGENFUNCTIONS OF THE WEIL REPRESENTATION OF UNITARY GROUPS OF ONE VARIABLE, Transactions of the American Mathematical Society, 350(6), 1998, pp. 2393-2407
In this paper, we construct explicit eigenfunctions of the local Well
representation on unitary groups Of one variable in the p-adic case wh
en p is odd. The idea is to use the lattice model, and the results wil
l be used to compute special values of certain Hecke L-functions in se
parate papers. We also recover Moen's results on when a local theta li
fting from U(1) to itself does not vanish.
