,Let’s Learn to Count,though its contents are elementary, we warmly suggest to take a look at the chapter. Our approach consists in trying to describe every combinatorial problem by means of sets of (ordered) sequences, or (unordered) collections, and their dual concepts of sharings and compositions. Computations are suc

Stirling Numbers and Eulerian Numbers, an application of the concepts discussed here we state Faà di Bruno chain rule for the .-th derivative of a composite of .-times differentiable functions on .. In the last section we discuss Eulerian numbers and as an application we solve the famous problem of the Smith College diplomas, and we est

Manipulation of Sums,screte analogue of differential calculus. The discrete primitives are the tool that enable to compute finite sums. We examine in detail the case of the sums of powers of consecutive natural numbers: quite surprisingly this leads to the Stirling numbers of second kind. A section is devoted to the inv

Formal Power Series, on their algebraic properties and basic applications to combinatorics. The reader must not be confused by the many technical, though simple, details that are needed in a book to justify rigorously every step. In Chap. ., we have learned how to count sequences and collections with occupancy constrai
