Subdivisions of the spectra for cesaro, rhaly and weighted mean operators on c(0),c and l(P)
(SPRINGER INTERNATIONAL PUBLISHING AG, 2011)
There are many different ways to subdivide the spectrum of a bounded linear operator; some of them are motivated by applications to physics (in particular, quantum mechanics). In this study, the relationship between the ...
Fixed Points of Proinov E-Contractions
(MDPI-SYMMETRY, 28 May 202)
In this paper, we consider a new type of Proinov contraction on the setting of a symmetrical
abstract structure, more precisely, the metric space. Our goal is to expand on some results from the
literature using admissible ...
THE SPECTRUM OF q–CESARO MATRICES ON ` c AND ITS VARIOUS SPECTRAL DECOMPOSITION FOR 0 < q < 1
(01.09.2021)
One of q-analogs of the Ces´aro matrix of order one is the triangular matrix with
nonzero entries cnk = qn−k/1+q+···+qn, 0 k n, where q ∈ [0,1] . In this article, we will determine
the spectrum of this matrix on the space ...
Inverse Nodal Problems for Dirac- Type Integro-Differential Operators with Linear Functions in the Boundary Condition
(Taylor&Francis, 2022)
In this article, Dirac-type integro-differential operator with linear
functions in the boundary condition is considered. We
obtain asymptotic expressions for the solution of the differential
system and derive the large ...
A partial inverse problem for non-self-adjoint Sturm–Liouville operators with a constant delay
(De Gruyter, 2023)
In this paper, we study a partial inverse spectral problem for non-self-adjoint Sturm–Liouville operators with a constant delay and show that subspectra of two boundary value problems with one common boundary condition are ...
