Bivariate Extension of the r-Dowling Polynomials and the Generalized Spivey's Formula [article]

Mahid M. Mangontarum
2020 arXiv   pre-print
In this paper, we extend the r-Dowling polynomials to their bivariate forms. Several properties that generalize those of the bivariate Bell and r-Bell polynomials are established.  ...  Finally, we obtain two forms of generalized Spivey's formula.  ...  When m = 1 and r = 0, this results to B n+1 (x, y) = n i=0 n i B i (x − 1)xy, (43) the bivariate extension of (2).  ...

A Family of the r-Associated Stirling Numbers of the Second Kind and Generalized Bernoulli Polynomials

Paolo Emilio Ricci, Rekha Srivastava, Pierpaolo Natalini
2021 Axioms  
Herein, we use the Blissard umbral approach and the familiar Bell polynomials. Links with available literature on this subject are also pointed out. The extension to the bivariate case is discussed.  ...  In this article, we derive representation formulas for a class of r-associated Stirling numbers of the second kind and examine their connections with a class of generalized Bernoulli polynomials.  ...  When j = 2 bivariate extensions of the Bernoulli and Euler polynomials were introduced [39] , the case of higher dimensions was also considered in [32] .  ...
