Query: Spherical Functions on 2-adic Ramified Hermetian Spaces   Y. Hironaka introduced the spherical functions on the p-adic space of
Hermitian matrices. For the space of 2\times2 Hermitian matrices, we complete
Hironaka's work by also considering the case of a wildly ramified quadratic
extension. We compute the spherical functions explicitly and obtain the
functional equations.
