Simultaneous approximation by Gauss–Weierstrass–Wachnicki operators

Abstract In this note, we spotlight a generalization of Weierstrass integral operators introduced by Eugeniusz Wachnicki. The construction involves modified Bessel functions. The operators are correlated with diffusion equation. Our…
