Plancherel formula for the Shehu transform

• Fourier transform and Plancherel Theorem

When we try to transfer these three concepts to a “curved manifold” M , the situation becomes instantly very complicated. Let us look for an appropriate class of M ’s for which we can expect satisfactory answers. We need the requirement to measure distances, so M should be Riemannian. In order to have a reasonable theory of selfadjoint operators on M we also need completeness. But still the cla...

Plancherel Formula for the 2 x 2 Real Unimodular Group.

The plancherel formula for sl(2) over a local field.

More than two decades ago, in his classical paper on the irreducible unitary representations of the Lorentz group, V. Bargmann initiated the concrete study of Fourier analysis on real Lie groups and obtained the analogue of the classical Fourier expansion theorem in the case of the Lorentz group. Since then the general theory for real semisimple Lie groups has been extensively developed, chiefl...

In HC], Harish-Chandra derived the Plancherel formula on p-adic groups. However, to have an explicit formula, one will have to compute the measures appearing in the formula. Here, we compute Plancherel measures on Sp 4 over p-adic elds explicitly.

Plancherel transform criteria for Weyl-Heisenberg frames with integer oversampling

We investigate the relevance of admissibility criteria based on Plancherel measure for the characterization of tight Weyl-Heisenberg frames with integer oversampling. For this purpose we observe that functions giving rise to such Weyl-Heisenberg frames are admissible with regard to the action of a suitably defined type-I discrete group G. This allows to relate the construction of Weyl-Heisenber...
