Shift Operators Defined in the Riordan Group and Their Applications

Research output: Journal ArticleArticlepeer-review

Abstract

In this paper, we discuss a linear operator T dened in Riordan group R by using the upper shift matrix U and lower shift matrix UT ; namely for each R 2 R, T : R 7! URUT . Some isomorphic properties of the operator T and the structures of its range sets for dierent domains are studied. By using the operator T and the properties of Bell subgroup of R, the Riordan type Chu-Vandermonde identities and the Riordan equivalent identities of Format Last Theorem and Beal Conjecture are shown. The applications of the shift operators to the complementary Riordan arrays and to the Riordan involutions and Riordan pseudo-involutions are also presented.
