Approximations of positive operators and continuity of the spectral radius II
Mathematische Zeitschrift, 1992 AbstractWe prove estimates on the speed of convergence of the ‘peripheral eigenvalues’ (and principal eigenvectors) of a sequence Tn of positive operators on a Banach lattice E to the peripheral eigenvalues of its limit operator T on E which is positive, irreducible and such that the spectral radius r(T) of T is a Riesz point of the spectrum of T (that

The Θ-transformation of certain positive linear operators
International Journal of Mathematics and Mathematical Sciences, 1996 The intention of this paper is to describe a construction method for a new sequence of linear positive operators, which enables us to get a pointwise order of approximation regarding the polynomial summator operators which have best properties of ...

Certain approximation properties of Brenke polynomials using Jakimovski–Leviatan operators
Journal of Inequalities and Applications, 2021 In this article, we establish the approximation by Durrmeyer type Jakimovski–Leviatan operators involving the Brenke type polynomials. The positive linear operators are constructed for the Brenke polynomials, and thus approximation properties for these ...

Statistical approximation by positive linear operators [PDF]
Studia Mathematica, 2004 The sequences of some classical approximation operators tend to converge to the values of the function they approximate, except perhaps at points of discontinuity, where in several cases such sequences do not converge to any value. Statistical convergence, which is a regular non-matrix summability method, has revealed effective to correct the lack of ...

Rate of approximation by a new sequence of linear positive operators [PDF]
, 2003 In the present paper, we study the rate of pointwise approximation by a new sequence of linear positive operators for functions of bounded variation. To prove the main result, we have used some results of probability theory. In the end, we also introduce

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Mixed Conformable Fractional Approximation Using Positive Sublinear Operators [PDF]
, 2018 Here we consider the approximation of functions by positive sublinear operators with applications to a large variety of Max-Product operators under mixed conformable fractional differentiability. These are examples of positive sublinear operators.
