We provide algorithms for performing computations in generalized numerical semigroups, that is, submonoids of ℕ d with finite complement in ℕ d.These semigroups are affine semigroups, which in ...

For a quantum Markov semigroup on the algebra with a faithful invariant state ρ, we can define an adjoint with respect to the scalar product determined by ρ. In this paper, we solve the open problems ...

Moreover, these solutions are Lipschitz continuous on any finite time interval and right differentiable. Our approach uses the theory of maximal monotone operators and the Crandall-Pazy theorem about ...
