the aim of this paper is to analyze the undamped second order descriptor systems to show the possibility of transform an undamped second order descriptor system to a pure first order descriptor system ,on different ways, while stating some of its benefits. meanwhile we will introduce pure first order systems and undamped second order systems and indicate that under some assumptions every undamp...

The argument runs as follows: (i) underlying representations are prosodified; (ii) this makes them relatively ill-formed; (iii) so representations can be represented purely in terms of ill-formedness. Step (i) brings to its logical...
