Distribution Functions for Random Variables for Ensembles of positive Hermitian Matrices

, 1997
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

Finite-dimensional perturbations of linear operators and some applications to boundary integral equations [PDF]

, 1999
Finite-dimensional perturbing operators are constructed using some incomplete information about eigen-solutions of an original and/or adjoint generalized Fredholm operator equation (with zero index).

Unbounded generalized B-Fredholm operators

Extracta Mathematicae
In this paper, we investigate a new class of unbounded linear operators, that is, the unbounded generalized B-Fredholm operators in Banach space. More explicitly, we provide a characterization of this class of operators and some of its basic properties ...

Fredholm conditions on non-compact manifolds: theory and examples

, 2017
We give explicit Fredholm conditions for classes of pseudodifferential operators on suitable singular and non-compact spaces. In particular, we include a "user's guide" to Fredholm conditions on particular classes of manifolds including asymptotically ...

On the Convergence of the Approximate Solution to the Optimization Problem for Oscillatory Processes

Қарағанды университетінің хабаршысы. Математика сериясы
This article addresses the non-linear optimization problem of oscillatory processes governed by partial integro-differential equations involving a Fredholm integral operator. A distinctive feature of the problem is that both the objective functional and

General note on the theorem of Stampfli

Journal of Inequalities and Applications, 2016
It is well known that for every bounded operator A in L ( H ) $L(H)$ , there exists a compact operator K in K ( H ) $K(H)$ such that the Weyl spectrum σ W ( A ) $\sigma_{W}(A)$ of the operator A coincides with the spectrum σ ( A + K ) $\sigma(A+K)$ of ...

Some Classes of Solutions to the Toda Lattice Hierarchy

, 1996
We apply an analogue of the Zakharov-Shabat dressing method to obtain infinite matrix solutions to the Toda lattice hierarchy. Using an operator transformation we convert some of these into solutions in terms of integral operators and Fredholm ...
