Query: A theorem on approximation by algebraic polynomials of functions with
  given generalised modulus of smoothness   We introduce an asymmetric operator of generalised translation, define the
generalised modulus of smoothness by its means, and obtain the direct and
inverse theorems in approximation theory for it.
