Title in Portuguese
Formalismo hamiltoniano em física de plasmas
Keywords in Portuguese
Física de plasmas
Abstract in Portuguese
A representação de Clebsch é estendida ao modelo magneto- hidrodinãmico com viscosidade de giro e ao modelo de dois fluidos . Com essa representação são obtidas as formulações Hamiltonianas canônicas para esses modelos, usados em Física de Plasmas. O colchete de Poisson não- canônico, deduzido para a magneto- hidrodinâmica com viscosidade de giro , é utilizado para se obter constantes de movimento e invariantes de Casimir . A influência da viscosidade de giro no espectro das oscilações em tokamaks é analisada neste trabalho.

Abstract in English
The Clebsch representation is extended to the gyroviscous magnetohydrodynamical model and to the two- fluid model. With this representation canonical Hamil tonian formulations are obtained for these mOO.els used in Plasma Physics. The non canonical Poisson bracket deduced for the gyroviscous magnetohydrodynamics is used to obtain constants of motion and Casimir invariants. The influence of the gyroviscosity in the tokamak oscillation spectr um is analyzed in this work .
