The duality principle for group representations developed in Dutkay et al.(J Funct Anal 257: 1133–1143, 2009), Han and Larson (Bull Lond Math Soc 40: 685–695, 2008) exhibits a fact that the well-known duality principle in Gabor analysis is not an isolated incident but a more general phenomenon residing in the context of group representation theory. There are two other well-known fundamental properties in Gabor analysis: the biorthogonality and the fundamental identity of Gabor analysis. The main purpose of this this paper is to show that these two fundamental properties remain to be true for general projective unitary group representations. Moreover, we also present a general duality theorem which shows that that muti-frame generators meet super-frame generators through a dual commutant pair of group representations. Applying it to the Gabor representations, we obtain thatis a frame forif and only ifis a Riesz sequence, andis a frame forif and only ifis a Riesz sequence, whereandis a pair of Gabor representations restricted to a time–frequency latticeand its adjoint latticein.
