Horário: das 17:05 às 17:25 horas

Local: Auditório do DM

Resumo: We present the concept of stability of solutions of quite general partial diferential equation problems, many of them arising in problems in physics. We will try to understand how little perturbations on an exact solution can lead, afther suffieciently large amount of time, to completely different qualitative properties of the solution and thus to different physical phenomena. We will see the three diferent type of instabilities that physical field theories can exhibit: tachions, goshts and strongly couppled degrees of freedom.
