Computational_algebraic_geometry.pdf

This book should be thought of as an advertisement for other, more advanced texts (or, perhaps, texts where details omitted here are carefully worked out!);there is nothing here that cannot be found elsewhere. What I hope is novel is the emphasis on working with a keyboard at hand to try out computations,the choice of topics, and the commingling of algebra, combinatorics, topology,and geometry.
