By Vincent Cossart (auth.), Antonio Campillo López, Luis Narváez Macarro (eds.)

The concentration of this quantity lies on singularity concept in algebraic geometry. It contains papers documenting contemporary and unique advancements and strategies in topics reminiscent of answer of singularities, D-module idea, singularities of maps and geometry of curves. The papers originate from the 3rd overseas convention on Algebraic Geometry held in l. a. Rábida, Spain, in December 1991. when you consider that then, the articles have passed through a meticulous strategy of refereeing and development, and so they were equipped right into a finished account of the state-of-the-art during this field.
