We introduce a framework for calculating sparse approximations to signals based on elements of continuous wavelet systems. The method is based on an extension of the continuous wavelet theory. In the new theory, the signal space is embedded in larger abstract signal space, which we call the window-signal space. There is a canonical extension of the wavelet transform on the window-signal space, ...

We give the inversion formula and Plancherel for hypergeometric Fourier transform associated with a root system of type $BC$, when multiplicity parameters are not necessarily non-negative.

Growth of Young diagrams, equipped with Plancherel measure, follows the automodel equation Kerov. Using technology unitary matrix model we show that such growth process is exactly same as gap-less phase in Gross-Witten and Wadia (GWW) model. The limit shape asymptotic diagrams corresponds to GWW transition point. Our analysis also offers an alternate proof theorem Vershik-Kerov Logan-Shepp. con...

In this paper, we are interested in the asymptotic size of the rows and columns of a random Young diagram under a natural deformation of the Plancherel measure coming from Hecke algebras. The first lines of such diagrams are typically of order n, so it does not fit in the context of the work of P. Biane and P. Śniady. Using the theory of polynomial functions on Young diagrams of Kerov and Olsha...

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...

The shifted Schur measure introduced in [TW2] is a measure on the set of all strict partitions λ = (λ1 > λ2 > · · · > λl > 0), which is defined by Schur Q-functions. The main aim of this paper is to calculate the correlation function of this measure, which is given by a pfaffian. As an application, we prove that a limit distribution of λj ’s with respect to a shifted version of the Plancherel m...
