Regularity of Solutions of Linear Second Order Elliptic and Parabolic Boundary Value Problems on Lipschitz Domains
Robin Nittka
For a linear, strictly elliptic second order differential operator in divergence form with bounded, measurable coefficients on a Lipschitz domain we show that solutions of the…

Properties of Representations of Operators acting between Spaces of Vector-Valued Functions
Delio Mugnolo, Robin Nittka
A well-known result going back to the 1930s states that all bounded linear operators mapping scalar-valued -spaces into -spaces are kernel operators and that in fact…

On the Banach-Mazur Type for Normed Spaces
Robin Nittka
In order to measure qualitative properties we introduce a notion of a type for arbitrary normed spaces which measures the worst possible growth of partial sums of sequences weakly…
