By Jocelyn Quaintance, Henry W. Gould

This ebook is a different paintings which supplies an in-depth exploration into the mathematical services, philosophy, and data of H W Gould. it truly is written in a mode that's available to the reader with uncomplicated mathematical wisdom, and but includes fabric that might be of curiosity to the professional in enumerative combinatorics. This ebook starts with exposition at the combinatorial and algebraic thoughts that Professor Gould makes use of for proving binomial identities. those strategies are then utilized to boost formulation which relate Stirling numbers of the second one sort to Stirling numbers of the 1st sort. Professor Gould's innovations additionally offer connections among either kinds of Stirling numbers and Bernoulli numbers. Professor Gould believes his examine luck comes from his instinct on how one can detect combinatorial identities.This publication will attract a large viewers and will be used both as lecture notes for a starting graduate point combinatorics type, or as a learn complement for the professional in enumerative combinatorics.
