Abstract:Let be a standard subspace in the complex Hilbert space and be a finite dimensional Lie group of unitary and antiunitary operators on containing the modular group of and the corresponding modular conjugation . We study the semigroup and determine its Lie wedge , i.e., the generators of its one-parameter subsemigroups in the Lie algebra of . The semigroup is analyzed in terms of antiunitary representations and their analytic extension to semigroups of the form , where is an -invariant closed convex cone. Our main results assert that the Lie wedge spans a -graded Lie subalgebra in which it can be described explicitly in terms of the involution of induced by , the generator of the modular group, and the positive cone of the corresponding representation. We also derive some global information on the semigroup itself.
