A characterization of real matrix semigroups
Benedict Bauer, Stefan Gerhold
We characterize all real matrix semigroups satisfying a mild boundedness assumption, without assuming continuity. Besides the continuous solutions of the semigroup functional equat…

The Fan-Taussky-Todd inequalities and the Lumer-Phillips theorem
Benedict Bauer, Stefan Gerhold
We argue that a classical inequality due to Fan, Taussky and Todd (1955) is equivalent to the dissipativity of a Jordan block. As the latter can be characterised via the zeros of C…

Small ball probabilities and large deviations for grey Brownian motion
Stefan Gerhold
We show that the uniform norm of generalized grey Brownian motion over the unit interval has an analytic density, excluding the special case of fractional Brownian motion. Our main…
