โฆ Synopsis
The theory of non symmetric Dirichlet forms is generalized to the non abelian setting, also establishing the natural correspondences among Dirichlet forms, sub-Markovian semigroups and sub-Markovian resolvents within this context. Some results on the allowed functional calculus for closed derivations on Hilbert algebras are obtained. Examples of non symmetric Dirichlet forms given by derivations on Hilbert algebras are studied.
