Potências simbólicas e suas interações

Abstract

The notion of symbolic power dates back to W. Krull, who used it in the proof of the famous theorem of principal ideal, this a crucial milestone in the short history of commutative algebra. Later, O. Zariski, M. Nagata, D. Rees and others have shown how this purely algebraic notion has important signi cance in algebraic geometry. In this paper we study the symbolic powers showing some of its most fundamental properties and their connections with various aspects of algebraic geometry and commutative algebra.
