The Extended Legendre-Stirling Numbers of the First Kind
The Legendre-Stirling numbers of the first kind PSn(j) are defined by the coefficients of Taylor expansion of the function x(x-2)(x-6)…(x(n-1)n) by Andrews and Littlejohn (see A combinatorial interpretation of the Legendre-Stirling numbers,Proc.Amer.Math.Soc,137: 2581-2590,2009).In this paper,two new kinds of numbers PS(j)-n(n≥0,j≥-1) and PS(j)-n(0≤n≤j) which are proposed with the coefficients of Laurent expansion of the function( x(x-2)(x-6)…(x-(n-1)n)-1,which are called the extended Legendre-Stirling numbers of the first kind.Several properties of the two new sequences are proved,such as the recurrence relations,vertical recurrence relation,forward difference.Also,this paper shows a relational expression of the Legendre-Stirling numbers of the extended first and second kinds.
