ON APPROXIMATION OF INTEGRABLE FUNCTIONS BY MODIFIED BERNSTEIN POLYNOMIALSSuresh Prasad SinghDepartment of Mathematics, Garhwal University, Sprinagar 246174, U.P. IndiaAbstract: We introduce a class of positive linear operators defined for functions integrable on the simplex $\Delta=\{(x_1,x_2) : x_1\geq 0, x_2\geq 0, x_1+x_2\leq 1\}$ and study some approximations theorems on it.
