Query: Plancherel decomposition of Howe duality and Euler factorization of
  automorphic functionals   There are several global functionals on irreducible automorphic
representations which are Eulerian, that is: pure tensors of local functionals,
when the representation is written as an Euler product $\pi = \otimes'_v \pi_v$
of local representations. The precise factorization of such functionals is of
interest to number theorists and is -- naturally -- very often related to
special values of $L$-functions.
  The purpose of this paper is to develop in full generality the Plancherel
formula for the Weil or oscillator representation, considered as a unitary
representation of a reductive dual pair, and to use it in order to demonstrate
a very general principle of Euler factorization: local factors are determined
via the Langlands correspondence by a local Plancherel formula. This pattern
has already been observed and conjectured in the author's prior work with
Venkatesh in the case of period integrals. Here, it is shown that the Rallis
inner product formula amounts to the same principle in the setting of global
Howe duality.
