Analytic vs. numerical solutions to a Sturm-Liouville transmission eigenproblem

6 years ago

AbstractAn elliptic one-dimensional second order boundary value problem involving discontinuous coefficients, with or without transmission conditions, is considered. For the…

Approximation operators constructed by means of Sheffer sequences

6 years ago

Abstract In this paper we introduce a class of positive linear operators by using the “umbral calculus”, and we study…

On an approximation operator and its Lipschitz constant

6 years ago

AbstractIn this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a…

Compound operators constructed with binomial and Sheffer sequences

6 years ago

AbstractIn this note we consider a general compound approximation operator using binomial sequences and we give a representation for its…

On compound operators depending on s parameters

6 years ago

AbstractIn this note we introduce a compound operator depending on s parameters using binomial sequences. We compute the values of…

Sheffer sequences, probability distributions and approximation operators

6 years ago

AbstractWe present a new method to compute formulas for the action on monomials of a generalization of binomial approximation operators…

Constraining Bose-Einstein condensate dark matter models with the galaxy rotation curves of the SPARC sample

6 years ago

AbstractIf dark matter did exist in the form of a self-interacting boson gas, when its temperature became lower than the…

On approximation by some Bernstein–Kantorovich exponential-type polynomials

6 years ago

AbstractSince the introduction of Bernstein operators, many authors defined and/or studied Bernstein type operators and their generalizations, among them are…

SERS assessment of the cancer-specific methylation pattern of genomic DNA: towards the detection of acute myeloid leukemia in patients undergoing hematopoietic stem cell transplantation

6 years ago

AbstractIn this label-free surface-enhanced Raman scattering (SERS) study of genomic DNA, we demonstrate that the cancer-specific DNA methylation pattern translates…

On some fixed point theorems for multi-valued operators by altering distance techique

7 years ago

AbstractThe aim of this paper is to present some sufficient conditions for the existence and uniqueness of fixed points for…
