Περίληψη :

Galactic discs are the major components of spiral and S0 galaxies. They harbour a number of substructures, such as spirals, bars, rings, boxy/peanut bulges, discy bulges etc, which not only look spectacular, but also, if adequately analysed, can reveal crucial information about the galaxy itself. Relying heavily on numerical simulations, I will review and discuss some of these structures, and what they can reveal about the general problem of galaxy evolution.
