In this paper we shall try to transpose the conditions of the existence of propagators for kernel on *-semigroups, notion introduced by P. Masani [6]. We will start with a few additional observations concerning *-represe...
We prove an existence and uniqueness result for an integral equation involving selfadjoint integral operators in LR^2(0,1). The proof of principal result uses a variational method in Hilbert space, finalized by applicati...
Starting with the Schurer's bivariate approximation formula, a cubature formula of Schurer type is constructed. When the approximated function is sufficiently differentiable, an upper bound estimation for the remainder t...
A new class of positive linear operators have been introduced which
contains a number of well known positive linear operators such as Gamma-Operators of
Muller, Post-Widder and Modi.ed Post-Widder Operators as partic...

PROPAGATORS AND DILATIONS ON PSEUDO-HILBERT SPACES
In this paper we shall try to transpose the conditions of the existence of propagators for kernel on *-semigroups, notion introduced by P. Masani [6]. We will start with a few additional observations concerning *-represe...
A FIXED POINT METHOD IN THE STUDY OF AN INTEGRAL EQUATION
We prove an existence and uniqueness result for an integral equation involving selfadjoint integral operators in LR^2(0,1). The proof of principal result uses a variational method in Hilbert space, finalized by applicati...
A NOTE ON THE SCHURER'S CUBATURE FORMULA
