We present the SP package which provides some functions on Schubert polynomials. These polynomials contain as a subfamily the Schur functions that are the fundamental symmetric functions. They are… (More)

Recent works in algebraic combinatorics have brought up to date the importance of certain planar structures, called ribbon tableaux, which are generalizations of Young tableaux. This paper gives an… (More)

We give several examples where PVM was successfully used as a tool for distributed computation of solutions of combinatorial problems. Involved topics are the computation of the solution of… (More)
