This book focuses on the special and unique potential that universities have to offer within the context of people fleeing their homes and seeking asylum and integration. Starting with social diversity as a prerequisite for European urban development

We study the one dimensional nonlinear Schr\"odinger equation with power nonlinearity $|u|^{\alpha - 1} u$ for $\alpha \in [1,5]$ and initial data $u_0 \in L^2(\mathbb{R}) + H^1(\mathbb{T})$. We show via Strichartz estimates that the Cauchy problem i

We introduce a Littlewood-Paley characterization of modulation spaces and use it to give an alternative proof of the algebra property, somehow implicitly contained in Sugimoto (2011), of the intersection $M^s_{p,q}(\mathbb{R}^d) \cap M_{\infty, 1}(\m

A result by Liskevich and Perelmuter from 1995 yields the optimal angle of analyticity for symmetric submarkovian semigroups on $L_p$, $1

Zeitgemäße Stadtplanungskonzepte setzen die städtebauliche Mischung als Grundprinzip voraus und erkennen darin eine zwar herausfordernde, aber notwendige Praxis. In der Umsetzung ist sie jedoch umstritten und bleibt oft unerreicht oder im Ergebnis

We show results on $L^p$-spectral multipliers for Maxwell operators with bounded measurable coefficients. We also present similar results for the Stokes operator with Hodge boundary conditions and the Lam\'e system. Here we rely on resolvent estimate
