✦ Synopsis

The Ising model on the square lattice decorated with randomly annealed diluted competing general integer or half-integer bond spin is studied. The exact phase diagrams of the critical temperature plotted against the competition parameter and against the concentration of decorating spins are evaluated analytically and fully analysed. Furthermore the exact, general ground state is obtained. * Work partially supported by CNPq, FINEP and FAPEMIG.
