Maria Crăciun • Journal of Numerical Analysis and Approximation Theory
(2004)
In this note we introduce a compound operator depending on \(s\)
parameters using binomial sequences. We compute the values of this
operator on the test functions, we give a convergence theorem and
a representation of the remainder in...
