Approximation by Certain Linear Positive Operators of Two Variables [PDF]
Abstract and Applied Analysis, 2014 We introduce positive linear operators which are combined with the Chlodowsky and Szász type operators and study some approximation properties of these operators in the space of continuous functions of two variables on a compact set. The convergence rate

Iteration of positive approximation operators [PDF]
Journal of Approximation Theory, 1970 AbstractWe present an analysis of the limit behavior of the k(n)-th iterates of positive linear approximation operators Ln, as n and k(n) tend to infinity. For various classes of operators the limit semigroup is explicitly identified. Two applications of the results are given: (a) identification of functions f satisfying Ln f ⩾ f for all n, for a ...

Approximation Strategy by Positive Linear Operators [PDF]
Journal of Function Spaces and Applications, 2013 Summary: Two important techniques to achieve the Jackson type estimation by Kantorovich type positive linear operators in \(L^p\) spaces are introduced in the present paper, and three typical applications are given.

Approximation by Positive Sublinear Operators [PDF]
, 2018 Here we study the approximation of functions by positive sublinear operators under differentiability. We produce general Jackson type inequalities under initial conditions. We apply these to a series of well-known Max-product operators. So our approach is quantitative by producing inequalities with their right hand sides involving the modulus of ...

Approximation theorems for positive operators on L-spaces [PDF]
Journal of Approximation Theory, 1990 For \(T\in {\mathcal L}(L^ p(m),L^ r(n))\), where (X,\({\mathcal A},m)\) and (Y,\({\mathcal B},n)\) are \(\sigma\)-finite mesure spaces, let \(M(T)=\{f\in L^ p(m):\| Tf\| =\| T\| \| f\| \}\) and \(J(T)=\{\sup p f: f\in M(T)\}\). A linear bounded operator T is said to be positive (T\(\geq 0)\) if Tf\(\geq 0\) whenever \(f\geq 0\).

Approximation of positive operators by analytic vectors
Karpatsʹkì Matematičnì Publìkacìï, 2020 We give the estimates of approximation errors while approximating of a positive operator $A$ in a Banach space by analytic vectors. Our main results are formulated in the form of Bernstein and Jackson type inequalities with explicitly calculated ...

Degree of L-approximation by certain positive convolution operators [PDF]
Journal of Approximation Theory, 1978 AbstractThe degree of Lp-approximation for a class of positive convolution operators is investigated. Recent results of De Vore, Bojanic, and Shisha for the uniform approximation by these operators and the K-functional of Peetre are employed to obtain the degree of approximation in terms of the integral modulus of smoothness.
