Fix a lattice, a bilinear polarization and Hodge numbers. The period domain consists of the <Hodge filtrations> with these dimensions satisfying orthogonality, opposition and positivity. It is an open subset of its <compact dual of a period domain>, described algebraically by the dimensions and orthogonality conditions alone.
