On explicit Fourier expansions of theta lifts to arising from elliptic newforms of level one
Henry H. Kim, Takuya Yamauchi
Using degenerate Whittaker functions and explicit computations of Eisenstein series, we obtain explicit formulas for the Fourier expansions of theta lifts to the special orthogonal…

Rationality of quaternionic Eisenstein series on
Henry H. Kim, Yi Shan
Let be the unitary group associated to a Hermitian space over a quadratic imaginary number field . We assume that 2 is unramified in , and the He…
