On Some Kn-Function Formulae

The object of this paper is to collect a number of results involving k_n-functions. These formulae do not seem to have been noted explicitly as yet. Some of them are obtained by the methods of operational calculus and others are derived from formulae involving W_k,m or M_k,m functions and Laguerre or Sonine polynomials given by Erdelyi, Howell, Bailey and Bateman.
