Summary:
Suppose F is a non-archimedean local field. The classical
Godement-Jacquet theory is that one can use Schwartz-Bruhat
functions on n × n matrices Mn(F) to define the local
standard L-functions on~GLn. The purpose of this partly
expository note is to give evidence that there is an analogous and
useful “approximate” Godement-Jacquet theory for the standard
L-functions on the special orthogonal groups SO(V): One
replaces GLn(F) with GSpin(V)(F) and Mn(F) with
Clif(V)(F), the Clifford algebra of V. More precisely, we
explain how a few different local unramified calculations for
standard L-functions on SO(V) can be done easily using
Schwartz-Bruhat functions on Clif(V)(F). We do not attempt any
of the ramified or global theory of L-functions on SO(V)
using Schwartz-Bruhat functions on Clif(V).
