Les equations polynomiales apparaissent dans de nombreux domaines, pour modeliser des contraintes geometriques, des relations entre des grandeurs physiques, ou encore des proprietes satisfaites par certaines inconnues. Cet ouvrage est une introduction aux methodes algebriques permettant de resoudre ce type d'equations. Nous montrons comment la geometrie des varietes algebriques definies par ces equations, leur dimension, leur degre, ou leurs composantes peuvent se deduire des proprietes des algebres quotients correspondantes. Nous abordons pour cela des methodes de la geometrie algebrique...

Algebraic Geometry provides an impressive theory targeting the understanding of geometric objects defined algebraically. Geometric Modeling uses every day, in order to solve practical and difficult problems, digital shapes based on algebraic models. In this book, we have collected articles bridging these two areas. The confrontation of the different points of view results in a better analysis of what the key challenges are and how they can be met. We focus on the following important classes of problems: implicitization, classification, and intersection. The combination of illustrative...
