Ulam-Hyers stability for partial differential inclusions

Electronic Journal of Qualitative Theory of Differential Equations, 2012
Using the weakly Picard operator technique, we will present Ulam-Hyers stability results for integral inclusions of Fredholm and Volterra type and for the Darboux problem associated to a partial differential inclusion.

Compactness property of the linearized Boltzmann operator for a diatomic single gas model

Networks and Heterogeneous Media, 2022
In the following work, we consider the Boltzmann equation that models a diatomic gas by representing the microscopic internal energy by a continuous variable I. Under some convenient assumptions on the collision cross-section \begin{document}$ \mathcal{B}

Arithmetic properties of Fredholm series for -adic modular forms [PDF]

, 2016
We study the relationship between recent conjectures on slopes of overconvergent -adic modular forms "near the boundary" of -adic weight space. We also prove in tame level 1 that the coeffcients of the Fredholm series of the U operator never vanish ...

On the partition function of the six-vertex model with domain wall boundary conditions

, 2004
The six-vertex model on an $N\times N$ square lattice with domain wall boundary conditions is considered. A Fredholm determinant representation for the partition function of the model is given.

Invertibility and Fredholm Property of Fock Toeplitz Operators

Mathematics, 2023
We characterize some necessary and sufficient conditions of invertible Toeplitz operators acting on the Fock space. In particular, we study the Fredholm properties of Toeplitz operators with BMO1 symbols, where their Berezin transforms are bounded ...

Covariant Dirac Operators on Quantum Groups

, 2011
We give a construction of a Dirac operator on a quantum group based on any simple Lie algebra of classical type. The Dirac operator is an element in the vector space $U_q(\g) \otimes \mathrm{cl}_q(\g)$ where the second tensor factor is a $q$-deformation ...

Numerical Treatment of Fixed Point Applied to the Nonlinear Fredholm Integral Equation

Fixed Point Theory and Applications, 2009
The authors present a method of numerical approximation of the fixed point of an operator, specifically the integral one associated with a nonlinear Fredholm integral equation, that uses strongly the properties of a classical Schauder basis in the Banach

Qualitative analysis of a fuzzy Volterra-Fredholm integrodifferential equation with an Atangana-Baleanu fractional derivative

AIMS Mathematics, 2022
The point of this work was to analyze and investigate the sufficient conditions of the existence and uniqueness of solutions for the nonlinear fuzzy fractional Volterra Fredholm integro-differential equation in the frame of the Atangana-Baleanu-Caputo ...

Fredholm theory and transversality for the parametrized and for the $S^1$-invariant symplectic action

, 2009
We study the parametrized Hamiltonian action functional for finite-dimensional families of Hamiltonians. We show that the linearized operator for the $L^2$-gradient lines is Fredholm and surjective, for a generic choice of Hamiltonian and almost complex ...
