Abstract:Dirichlet's principle, also known as a pigeonhole principle, claims that if n ∈ N item are put into m ∈ N containers, with n > m, then there is a container that contains more than one item. In this work, we focus rather on an inverse Dirichlet's principle (by switching items and containers), which is as follows: considering n ∈ N items put in m ∈ N containers, when n < m, then there is at least one container with no item inside. Furthermore, we refine Dirichlet's principle using discrete combinatorics within a… Show more
