Analyticity angle for non-commutative diffusion semigroups
نویسنده
چکیده
Under certain hypotheses, diffusion semigroups on commutative L-spaces are known to have an analytic extension for | arg z| < π 2 − arctan |p−2| 2 √ p−1 . In this paper it is shown that semigroups on non-commutative L-spaces have the same extension under suitable conditions. These conditions even lead to a new result in the commutative case. Further, some examples are considered.

Lp-analyticity of Schrödinger semigroups on Riemannian manifolds
We address the problems of extrapolation, analyticity, and Lp-spectral independence for C0-semigroups in the abstract context of metric spaces with exponentially bounded volume. The main application of the abstract result is Lp-analyticity of angle π 2 of Schrödinger semigroups on Riemannian manifolds with Ricci curvature bounded below, under the condition of form smallness of the negative part...
متن کاملOn Analytic Ornstein-uhlenbeck Semigroups in Infinite Dimensions
We extend to infinite dimensions an explicit formula of Chill, Fašangová, Metafune, and Pallara [2] for the optimal angle of analyticity of analytic Ornstein-Uhlenbeck semigroups. The main ingredient is an abstract representation of the Ornstein-Uhlenbeck operator in divergence form.
متن کاملPhysical Meaning of Quantum Space-Time Symmetries
A definition is given and the physical meaning of quantum transformations of a non-commutative configuration space (quantum group coactions) is discussed. It is shown that non-commutative coordinates which are transformed by quantum groups are the natural generalization of the notion of a tensor operator for usual groups and that the quantum group coactions induce semigroups of transformations ...

A ?semigroup is a semigroup whose lattice of congruences is a chain with respect to inclusion. Schein 9] and Tamura 11] have investigated commutative ?semigroups, Trotter 13] exponential, Nagy 4] weakly exponential and Bonzini and Cherubini Spoletini 2] nite ?semigroups. The pupose of the present paper is to investigate archimedean weakly commutative and H?commutative ?semigroups. 1 Weakly comm...
متن کاملFinitely Generated Weakly Reductive Commutative Semigroups∗
We give characterizations of the property of being weakly reductive for finitely generated commutative semigroups. As a consequence of these characterizations we obtain an algorithm for determining from a presentation of a finitely generated commutative semigroup whether it is weakly reductive. Furthermore, we present some connections between cancellative finitely generated commutative semigrou...
