A PLANCHEREL FORMULA ON Sp 4 AnneMarie Aubert and JuLee Kim
 

Summary: A PLANCHEREL FORMULA ON Sp 4
Anne­Marie Aubert and Ju­Lee Kim
Abstract. In [HC], Harish­Chandra derived a Plancherel formula on p­adic groups. How­
ever, to have an explicit formula, one will have to compute the measures appearing in the
formula. Here, we compute the Plancherel measures on Sp 4 over p­adic fields explicitly.
