1744b  Copositivity and Complete Positivity
[OWR201752] (2017)  (29 Oct  04 Nov 2017)A real matrix $A$ is called copositive if $x^TAx \ge 0$ holds for all $x \in \mathbb R^n_+$. A matrix $A$ is called completely positive if it can be factorized as $A = BB^T$ , where $B$ is an entrywise nonnegative matrix. ... 
1744a  Interplay between Number Theory and Analysis for Dirichlet Series
[OWR201751] (2017)  (29 Oct  04 Nov 2017)In recent years a number of challenging research problems have crystallized in the analytic theory of Dirichlet series and its interaction with function theory in polydiscs. Their solutions appear to require unconventional ... 
1743b  MiniWorkshop: Reflectionless Operators: The Deift and Simon Conjectures
[OWR201749] (2017)  (22 Oct  28 Oct 2017)Reflectionless operators in one dimension are particularly amenable to inverse scattering and are intimately related to integrable systems like KdV and Toda. Recent work has indicated a strong (but not equivalent) relationship ... 
1743a  MiniWorkshop: PDE Models of Motility and Invasion in Active Biosystems
[OWR201748] (2017)  (22 Oct  28 Oct 2017)Cell migration is crucial for the development and functioning of multicellular organisms; it plays an essential role in, e.g., morphogenesis, immune system dynamics, wound healing, angiogenesis, bacterial motion and biofilm ...
