Abstract: A number of theoretical and simulation results on star and structure formation in galaxy interactions and mergers are reviewed. The role of gravity torques and ISM turbulence in galaxy interactions, in addition to the tidal field, are highlighted. Interactions can drive gas inflows towards the central kpc and trigger a central starburst, the intensity and statistical properties of which are discussed. Outside of the central kpc, many structures can form inside tidal tails, collisional rings and bridges, including super star clusters and tidal dwarf galaxies. Their formation mechanisms and long-term evolution are discussed.
