Abstract
In the given note, we present the Durrmeyer modification of Lupaş type operators having Pochhammer \(k-\)symbol. We study convergence, asymptotic result and error of approximation in terms of first order modulus of continuity for these operators. Also, we estimate the approximation behavior of these operators in two variables in terms of complete and partial modulus of continuity. At last, we unveil some numerical examples with graphs to verify our results.
