  • Approximation of the Urysohn operator by operator polynomials of Stancu type 
    Demkiv, I.I.; Makarov, V.L. (Український математичний журнал, 2012)
    We study a one-parameter family of positive polynomial operators of one and two variables that approximate the Urysohn operator. In the case of two variables, the integration domain is an “isosceles right triangle.” As a ...
