The Positive Maximum Principle on Lie Groups and Symmetric Spaces [PDF]

open access: yes, 2019
In this thesis we will use harmonic analysis to get new results in probability on Lie groups and symmetric spaces. We will establish necessary and sufficient conditions for the existence of a square integrable K-bi-invariant density of a K-bi ...

Representations of differential operators on a Lie group

open access: yes, 1975
In this paper we apply the theory of second-order partial differential operators with nonnegative characteristic form to representations of Lie groups. We are concerned with a continuous representation U of a Lie group G in a Banach space B. Let E be the

Safety criteria for aperiodic dynamical systems [PDF]

open access: yes
The use of dynamical system models is commonplace in many areas of science and engineering. One is often interested in whether the attracting solutions in these models are robust to perturbations of the equations of motion.

ON RELATIONS BETWEEN URBANIK AND MEHLER SEMIGROUPS

open access: yes, 2009
It is shown that operator-selfdecomposable measures or, more precisely, their Urbanik decomposability semigroups induce general-ized Mehler semigroups of bounded linear operators.

REGULARIZED FUNCTIONAL CALCULI, SEMIGROUPS, AND COSINE FUNCTIONS FOR PSEUDODIFFERENTIAL OPERATORS

open access: yes, 2020
. Let iA j (1 ≤ j ≤ n) be generators of commuting bounded strongly continuous groups, A ≡ (A 1 , A 2 , ..., A n ). We show that, when f has sufficiently many polynomially bounded derivatives, then there exist k, r > 0 such that f (A) has a (1+|A| 2 ) −
