Abstract:
Touchard generalized the Bell polynomials in order to give some
combinatorial interpretation on permutations. Chrysaphinou
introduced and studied a class of polynomials related to Touchard's
generalization. In the present paper, we establish some relations
between Touchard polynomials, Bell polynomials and the polynomials of
binomial type. Several identities and relations with Stirling numbers
are obtained.
