On the order of approximation by modified summation-integral-type operators based on two parameters

Demonstratio Mathematica, 2023
In this article, we the study generalized family of positive linear operators based on two parameters, which are a broad family of many well-known linear positive operators, e.g., Baskakov-Durrmeyer, Baskakov-Szász, Szász-Beta, Lupaş-Beta, Lupaş-Szász ...

Starlikness Associated with Cosine Hyperbolic Function

Mathematics, 2020
The main contribution of this article is to define a family of starlike functions associated with a cosine hyperbolic function. We investigate convolution conditions, integral preserving properties, and coefficient sufficiency criteria for this family ...

Tests of Basic Quantum Mechanics in Oscillation Experiments [PDF]

, 1997
According to standard quantum theory, the time evolution operator of a quantum system is independent of the state of the system. One can, however, consider systems in which this is not the case: the evolution operator may depend on the density operator ...

Statistical weighted A-summability with application to Korovkin’s type approximation theorem

Journal of Inequalities and Applications, 2016
We introduce the notion of statistical weighted A-summability of a sequence and establish its relation with weighted A-statistical convergence. We also define weighted regular matrix and obtain necessary and sufficient conditions for the matrix A to be ...

Construction of the Vacuum String Field Theory on a non-BPS Brane [PDF]

, 2002
In the framework of the Sen conjectures a construction of vacuum superstring field theory on a non-BPS brane is discussed. A distinguished feature of this theory is a presence of a ghost kinetic operator mixing GSO+/- sectors.

Probing N=4 SYM With Surface Operators [PDF]

JHEP 0810:048,2008, 2008
In this paper we study surface operators in N=4 supersymmetric Yang-Mills theory. We compute surface operator observables, such as the expectation value of surface operators, the correlation function of surface operators with local operators, and the correlation function of surface operators with Wilson and 't Hooft loops.
