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…

On the Fourier expansion of Gan-Gurevich lifts on the exceptional group of type

Henry H. Kim, Takuya Yamauchi

By using the degenerate Whittaker functions, we study the Fourier expansion of the Gan-Gurevich lifts which are Hecke eigen quaternionic cusp forms of weight (, even)…

Restriction of modular forms on to

Henry H Kim, Takuya Yamauchi

In this paper, we study the restriction of modular forms such as Ikeda type lifts and the Eisenstein series on the exceptional group of type to the symplectic group $Sp_6…

Central limit theorem for Hecke eigenvalues

Henry H. Kim, Satoshi Wakatsuki, Takuya Yamauchi

In this paper, we obtain the central limit theorem of Hecke eigenvalues in very general setting of split simple algebraic groups over , using irreducible characters of…
