Elliptic G-Operators on Manifolds with Isolated Singularities

Современная математика: Фундаментальные направления, 2016
We study elliptic operators on manifolds with singularities such that a discrete group G acts on the manifold. Following the standard elliptic theory approach, we de ne the Fredholm property of an operator by its principal symbol.

Alternativa de Fredholm para operadores monotonos [PDF]

, 1987
Several conditions are imposed on a non-linear operator of a reflexive Banach Space into its dual which allow to establish a Fredholm alternative for such an operator. Then an application is given to a problem in Algebraic GeometrySe dan condiciones para

A fixed-point type result for some non-differentiable Fredholm integral equations

Mathematical Modelling and Analysis
In this paper, we present a new fixed-point result to draw conclusions about the existence and uniqueness of the solution for a nonlinear Fredholm integral equation of the second kind with non-differentiable Nemytskii operator.

Fredholm linear operators associated with ordinary differential equations on noncompact intervals

Electronic Journal of Differential Equations, 1999
In the noncompact interval $J=[a,infty )$ we consider a linear problem of the form $Lx=y,; x in S$, where $L$ is a first order differential operator, $y$ a locally summable function in $J$, and $S$ a subspace of the Fr'{e}chet space of the locally ...

On Semi-Fredholm Operators [PDF]

, 1992
VIe prove that every semi-Fredholm operator on a.n arbitrary Banach space can be approxima.ted by injective or surjective operators. In the case of a complex separable Hilbert space, we show that the set of semi-Fredholm operators having a fixed index is

Convergence analysis of the Legendre wavelets method for a class of Fredholm-Volterra integro-differential equations of fractional-order

Miskolc Mathematical Notes
In this paper, we develop a Legendre wavelets method for the numerical solution of Fredholm-Volterra integro-differential equations of fractional order. The Caputo sense is used to explain the fractional derivative operator.

Evaluation of integrals for the emptiness formation probability in the square-ice model

Nuclear Physics B
We study the emptiness formation probability (EFP) in the six-vertex model with domain wall boundary conditions. We present a conjecture according to which at the ice point, i.e., when all the Boltzmann weights are equal, the known multiple integral ...
