Key ideas from these two areas provide the basis for a gen- eral scheme for the specication and representation of mathematical structures. The philosophy underlying the design of Magma is based on concepts from Universal Algebra and Category Theory. The design is intended to provide a mathematically rigorous environment for computing with algebraic struc- tures (groups, rings, elds, modules and algebras), geometric structures (varieties, special curves) and combinatorial structures (graphs, designs and codes). c 1997 Academic Press Limited Magma is a new software system for computational algebra, the design of which is based on the twin concepts of algebraic structure and morphism. Particular attention is given to the constructors for structures, maps, and sets. In the rst of two papers on Magma, a new system for computational algebra, we present the Magma language, outline the design principles and theoretical background, and indicate its scope and use. We felt it would be nice to add more material and The eight lectures on monomial ideals given there by Bernd Sturmfels were later written up by Ezra Miller and David Perkinson and published in. This project started at the COCOA summer school in Torino, Italy, in June 1999. Our exposition mainly concerns combinatorially defined ideals and their quotients, with a focus on numerical invariants and resolutions, especially under gradings more refined than the standard integer grading. The purpose of this volume is to provide a selfcontained introduction to some of the resulting combinatorial techniques for dealing with polynomial rings, semigroup rings, and determinantal rings. New methods have evolved out of an influx of ideas from such diverse areas as polyhedral geometry, theoretical physics, representation theory, homological algebra, symplectic geometry, graph theory, integer programming, symbolic computation, and statistics. In subsequent years, Celentano and Mori played together in 10 more films: “Super Robbery in Milan”, “The Story of Love and Knives”, “Rugantino”, “Emigrant”, “Hurry Before Your Wife Returns”, “Noble Venetian”, “Mad Man” Geppo”, “Innkeeper”, “Grand Hotel Excelsior”, “Joan Louis”.The last decade has seen a number of exciting developments at the intersection of commutative algebra with combinatorics. Adriano played an artist, and Claudia – a woman who comes to him with a child in her arms and declares what a terrible father he is. And for Mori, the film became her second serious work, before which she appeared only in episodes. He also managed to found his own music company, Clan Celentano. By that time, Celentano was already a famous actor, and his records were played in every Italian family. However, the heart of a guy with a “stunning grin”, as he was nicknamed in the press, was forever occupied by the sultry black-eyed beauty Claudia Mori.Īdriano and Claudia met on the set of the 1963 film Some Strange Man. Celentano was not distinguished by beauty in its canonical sense, but he had such charisma that he had no fewer fans than the handsome Alain Delon and the brutal Jean-Paul Belmondo. Adriano Celentano starred in almost sixty films, the most famous of which are Bluff, Velvet Hands, Ace, and, of course, The Taming of the Shrew.
