Abstract

The Reissner-Nordström black hole describes the gravitational and 
electromagnetic fields created by a spherically symmetric object 
governed by two parameters: its mass and electric charge. 
Generalizations of this solution through non-linear electrodynamics and 
their non-abelian generalizations have received a considerable interest 
in the last decades. In this talk I will give an overview of the current 
state of the topic and describe my own contributions to it. In 
particular, I shall describe a general procedure which allows to 
classify and qualitatively characterize the whole family of non-linear 
electrodynamics defined as arbitrary functions of the two field 
invariants and satisfying certain requirements for physical consistence 
of the theories. Through this procedure it is possible to study several 
features of the black holes including its metric structure and 
thermodynamics without explicitly fixing the lagrangian density 
function. Some explicit examples are given. Finally I will describe 
applications of this method to other interesting cases, such as 
generalized non-abelian gauge fields, and to other gravity theories such 
as the Lovelock one.
