A class of linear positive operators
Mathematical Notes of the Academy of Sciences of the USSR, 1988The author introduces and investigates two new classes of positive, linear operators that are similar (with respect to their spectral properties) to classes of quasi-sign-regular and quasi-totally-positive operators.

On the Approximation by Linear Positive Operators
1970This paper is concerned with some properties of linear positive operators which are in analogy with the well-known Bernstein operator. Let ℑ j (I j ), j = 1,2, denote two linear spaces of real functions defined on the sets I j , j = 1,2, of points of the real axis. Let L n :ℑ 1 (I 1 ) →ℑ 2 (I 2 ), n = 1,2,..., be a sequence of linear positive operators

Degeneracy of positive linear operators
1998A survey of results, obtained by the authors in the topic of degeneracy of positive linear operators, is given. It is shown that degeneracy is not only a privilege of Bernstein operators. Another type of generalization deals with multidimensional Bernstein polynomials over simplices.

On the position of the space of representable operators in the space of linear operators
1997The author studies complementability of the space \(R(L^1 (\lambda),Y)\) of representable operators in the space of all bounded operators \(L(L^1 (\lambda),Y)\). It is given a number of examples when \(R(L^1 (\lambda),Y)\) is complemented in \(L(L^1 (\lambda),Y)\), extending the known case \(Y=L^1 (\mu)\). For instance, when \(Y\) is a predual of a \(W^
