Journal of Lie Theory 23 (2013), No. 2, 493--505 Copyright Heldermann Verlag 2013 A Plancherel Formula for Representative Functions on Semisimple Lie Groups Robert W. Donley, Jr. 344 Grove Street, #20, Jersey City, NJ 07306, U.S.A. rdonleyjr@gmail.com A Plancherel formula is given for representative functions on a connected semisimple Lie group G. Since the matrix coefficients for the irreducible finite-dimensional representations are not necessarily square-integrable, an alternative to the Schur Orthogonality Relations is given using invariant differential operators. The corresponding operator analysis is summarized. Keywords: Semisimple Lie group, Schur orthogonality relations, matrix coefficient, representative function, Plancherel formula.
