1. Introduction:

The Fourth International Winter Conference on Mathematical Methods in Physics will happen at Centro Brasileiro de Pesquisas Físicas (CBPF), in Rio de Janeiro, being hosted by its Coordination of Fields and Particles (CCP/CBPF), between 9 and 13 of August, 2004. It will cover many different but related subjects such as Methods of Spectral and Group Theory, Topology, Differential and Algebraic Geometry and in Field Theory, Quantum Gravity, String Theory and Cosmology. It is  the fourth event in a series of conferences on Mathematical Methods in Physics that begun in Londrina (PR - Brazil)  in 1999.

The conference is structured in 9 plenary talks of 1h and 27 short seminars of 30 minutes, given by proeminent brazilian and foreign researchers. As we are interested in the most actual picture of the area, we invited many foreign speakers, all of them very experienced and of recognized leadership. A pannel section is also going to happen, to allow exposition of  ideas and results of the other participants.
