We introduce a class of operators, called l-Hankel operators, as those that satisfy the operator equation S g X -XS=lX, where S is the unilateral forward shift and l is a complex number. We investigate some of the properties of l-Hankel operators and show that much of their behaviour is similar to t

In this paper, we use a probabilistic setting to introduce a double sequence Ž ² k : . L of linear polynomial operators which includes, as particular cases, the n classical Bernstein operators, the Kantorovic operators, and the operators recently ǐntroduced by Cao. For these operators, we discuss se
