Several explicit formulae of Cauchy polynomials in terms of {r}-Stirling numbers

The integer values of Cauchy polynomials are expressed in terms of ({r})-Stirling numbers of the first kind. Several relations between the integral values of Bernoulli polynomials and those of Cauchy polynomials are obtained in terms of ({r})-Stirling numbers of both kinds. Also, we find a relation between the Cauchy polynomials and hyperharmonic numbers.
