TY - JOUR T1 - Approximation by $(p,q)$-Lupac{s} Stancu Operators TT - JF - IJMSI JO - IJMSI VL - 14 IS - 2 UR - http://ijmsi.ir/article-1-1012-en.html Y1 - 2019 SP - 43 EP - 60 KW - $(p KW - q)$-Integers KW - Lupac{s} $(p KW - q)$-Bernstein Stancu operators KW - Statistical approximation KW - Korovkin's type approximation. N2 - In this paper, $(p,q)$-Lupas Bernstein Stancu operators are constructed. Statistical as well as other approximation properties of $(p,q)$-Lupac{s} Stancu operators are studied. Rate of statistical convergence by means of modulus of continuity and Lipschitz type maximal functions has been investigated. M3 ER -
