Solvability of A Nonlocal Problem By A Novel Concept of Fundamental Function
(Georgian Natl Acad Sciences, 2018)Cauchy function, Green function and Riemann function are the several of the fundamental functions used frequently in the expression of a fundamental solution in the literature. In order to construct such functions, various ... -
Invariant subspaces of operators quasi-similar to L-weakly and M-weakly compact operators
(Scientific Technical Research Council Turkey-Tubitak, 2018)Let T be an L-weakly compact operator defined on a Banach lattice E without order continuous norm. We prove that the bounded operator S defined on a Banach space X has a nontrivial closed invariant subspace if there exists ... -
Isotropic Smarandache Curves in the Complex 4-Space
