The refined Stirling numbers of the first kind specify the number of permutations of n indices possessing m i cycles whose lengths modulo k are congruent to i; i ΒΌ 0; 1; 2; . . . ; k Γ 1: The refined Stirling numbers of the second kind are similarly defined in terms of set-partitions and the cardi
The main object of this paper is to give explicit formulas for the number of unlabelled bicolored (unrooted) plane trees with given degree distributions (1'12iz., . ; 1/12'2.1 ,). These trees are closely related to the Shabat polynomials, i.e., ~1~~~s over 8: having at most two critical values (cf.
