Multivariate Operator Theory
While the study of operator theory on Hilbert space has been underway for more than a hundred years, multivariate operator theory the study of more than one operator at a tim is of more recent origin. The study of self-adjoint algebras emerged in the late thirties in the works of Murray-von Neumann and Gelfand-Naimark. A couple of decades later, non self-adjoint algebras enjoyed considerable de...
متن کاملOn the Iterative Combinations of Baskakov Operator 53 2 A Set of Lemmas
In the present paper, we obtain a quantitative result and asymp-totic approximation of sufficiently smooth functions by Baskakov operator.
متن کاملOn Certain Baskakov-durrmeyer Type Operators
This paper is a study of the degree of approximation by the linear combinations of the derivatives of certain Durrmeyer type integral modification of the Baskakov operators in terms of the higher order modulus of smoothness.
متن کاملApproximation and Shape Preserving Properties of the Truncated Baskakov Operator of Max-product Kind
Starting from the study of the Shepard nonlinear operator of maxprod type in [2], [3], in the recent monograph [4], Open Problem 5.5.4, pp. 324-326, the Baskakov max-prod type operator is introduced and the question of the approximation order by this operator is raised. The aim of this note is to obtain the order of uniform approximation Cω1(f ; 1 √ n ) (with the explicit constant C = 24) of an...
متن کاملMultivariate Operator-Self-Similar Random Fields
Multivariate random fields whose distributions are invariant under operatorscalings in both time-domain and state space are studied. Such random fields are called operator-self-similar random fields and their scaling operators are characterized. Two classes of operator-self-similar stable random fields X = {X(t), t ∈ R} with values in R are constructed by utilizing homogeneous functions and sto...
