Sauda,c~oes, O prof. Rousseau me propôs este problema. Alguma sugestão/solução? Poderíamos ter uma colaboração individual/da lista no tal jornal. Eu começaria tentando uma solução por indução. [ ]'s Lu'is Dear Luis: I am just in the process of writing up some solutions of a problem in SIAM Problems and Solutions (an electronic publication that I edit). It occurred to me that you might like to find your own solution, which I would then be glad to publish. The problem came from Jonathan Borwein. You need to show that for each N \geq 1 the sum of the infinite series \sum_{k=0}^{\infty} k^k/((k+N)!e^k) can be expressed as P_N(e) where P_N is a polynomial of degree N with rational coefficients.
