On the Inverse and Determinant of Certain Truncated Wiener-Hopf Operators
نویسنده
چکیده
The solution of a problem arising in integrable systems [10] requires the asymptotics as α → ∞, with very small error, of the inverses and determinants of truncated Wiener-Hopf operators Wα(σ) acting on L (0, α), both in the regular case (where the Wiener-Hopf operator W (σ) on L2(R) is invertible) and in singular cases. This paper treats two cases where σ has simple Fisher-Hartwig singularities, one double zero or two simple zeros.

Determinants of Airy Operators and Applications to Random Matrices
The purpose of this paper is to describe asymptotic formulas for determinants of certain operators that are analogues of Wiener-Hopf operators. The determinant formulas yield information about the distribution functions for certain random variables that arise in random matrix theory when one rescales at “the edge of the spectrum”.
متن کاملOn the Inverse and Determinant of a Truncated Wiener-Hopf Operator
This paper focuses on the case where σ has the simplest Fisher-Hartwig singularity, one double zero. The method of [6] gives a first-order asymptotic result for the inverse. More recently Rambour and Seghier [5] found analogous and sharper results for the Toeplitz analogue. Neither of these serves our present purpose, which is to find a formula that holds uniformly throughout (0, α) with very s...
متن کاملA Note on Wiener-hopf Determinants and the Borodin-okounkov Identity
Recently, a beautiful identity due to Borodin and Okounkov was proved for Toeplitz determinants which shows how one can write a Toeplitz determinant as a Fredholm determinant. In this note we generalize this to the Wiener-Hopf case. The proof in the Wiener-Hopf case follows identically with the second one given in [1]. We include it here for completeness sake and because the nature of the ident...
متن کاملDistribution Functions for Random Variables for Ensembles of Positive Hermitian Matrices
Distribution functions for random variables that depend on a parameter are computed asymptotically for ensembles of positive Hermitian matrices. The inverse Fourier transform of the distribution is shown to be a Fredholm determinant of a certain operator that is an analogue of a Wiener-Hopf operator. The asymptotic formula shows that up to the terms of order o(1), the distributions are Gaussian.

whenever Φ is such that this extends to a bounded operator on Lpr0, asq. Whenever a is of no importance we will omit it from the notation. We abbreviate by saying that WΦ is a TWH-operator. These operators (or rather, unitarily equivalent ones) also go under the name finite interval convolution operators, truncated Hankel operators or Toeplitz operators on the Paley-Wiener space. See e.g. [1, 2...
