Combinatorialization of Sury and McLaughlin identities, general linear recurrences in a unified approach
Sudip Bera
In this article we provide with combinatorial proofs of some recent identities due to Sury and McLaughlin. We show that, the solution of a general linear recurrence with constant c…

Generalized power sum and Newton-Girard identities
Sudip Bera, Sajal Kumar Mukherjee
In this article we prove an algebraic identity which significantly generalizes the formula for sum of powers of consecutive integers involving Stirling numbers of the second kind.…
