Conhecendo as Equações Algébrico-Diferenciais

Abstract

The Differential Algebraic Equations are greatly important although there is very little study about them, but in the last few years we can notice an increase of interest in studying them. The aim of this article is to catch the interest of new researchers towards this area, to introduce the main types of Differential Algebraic Equations and the concept of index, which makes the Ordinary Differential Eguations a particular class of Differential Algebraic Equations.
