Multidimensional integro-differential equations are obtained when the unknown function of several independent variable and/or its derivatives appear under an integral sign. When the differentiation or integration operators or both are of fractional o

Weighted pseudo-almost periodic solutions for some neutral partial functional differential equations

Electronic Journal of Differential Equations, Vol 2012, Iss 47,, Pp 1-13 (2012)
In this article we study the existence of weighted pseudo almost periodic solutions of an autonomous neutral functional differential equation with Stepanov-Weighted pseudo almost periodic terms in a Banach space. We use the contraction mapping princi

In this paper, we investigate the essential spectra of some matrix operators on Banach spaces. The results obtained are used for describing the essential spectra of differential operators.

For each finite dimensional real vector space X we construct a C*-algebra A graded by the lattice of all subspaces of X and we compute its quotient with respect to the algebra of compact operators. This allows one to describe the essential spectrum a

In this work, we present a new concept of measure-ergodic process to define the space of measure pseudo almost periodic process in the p-th mean sense. We show some results regarding the completeness, the composition theorems and the invariance of th

We prove that it is always possible to add some divergence free drift vector eld to some spherical Dirichlet problem, such that the resulting principal eigenvalue lies above a prescribed bound. The drift vector eld can be chosen to vanish on the boun

We consider the notion of $$\chi$$ -completeness of a locally finite graph and we extend this notion to the weighted magnetic graph. Moreover, we establish a link between the magnetic adjacency matrix on line graph and the magnetic discrete Laplacian

We use C*-algebras to determine non-propagation estimates for a certain class of generalized Schr?dinger operators acting on L2(x) , where X is a locally compact group. In particular, the Schr?dinger operators on trees are included.
