As a continuation of the very recent papers of the author [22] and [23], we estimate their pointwise convergence to functions f and psi o broken vertical bar f broken vertical bar having derivatives are of bounded (Jordan) variation on the interval [0, 1] .Here psi o broken vertical bar f broken vertical bar denotes the composition of the functions psi and broken vertical bar f broken vertical bar The function : R-0(+)-> R-0(+) is continuous and concave with psi(0) = 0, psi(u) > 0 for u > 0 : This study can be considered as an extension of the related results dealing with the classical Durrmeyer operators.eninfo:eu-repo/semantics/openAccessNonlinear Durrmeyer OperatorsBounded Variation(L-psi) Lipschitz ConditionPointwise ConvergenceApproximation properties of a certain nonlinear Durrmeyer operatorsArticle10.2298/FIL1705367K315136713802-s2.0-85014735220Q3WOS:000397996300022Q3
