Formation and evolution mechanisms of barred spiral galaxies, such bars respond to angular momentum loss to the spiral structure is also considered. Finally the Galactostrophic approximation is introduced and guiding centres are shown to follow Ergos curves. Lindblad-like epicyles about such curves yield a new integral for the stellar dynamic of barred galaxi

Hydrodynamical simulations of the barred spiral galaxy NGC 1365,sing the FS2 code originally written by G.D. van Albada. We find good agreement between observations and models, both concerning the morphology and the velocity field. Contrary to observations, the pure bar perturbed models cannot drive an inner arm across corotation. Models having both a bar and sp
