Type semigroups for twisted groupoids and a dichotomy for groupoid C*-algebras Open
We develop a theory of type semigroups for arbitrary twisted, not necessarily Hausdorff étale groupoids. The type semigroup is a dynamical version of the Cuntz semigroup. We relate it to traces, ideals, pure infiniteness, and stable finite…

Isomorphism and stable isomorphism in "real" and "quaternionic" K-theory Open
We find lower bounds on the rank of a "real" vector bundle over an involutive space, such that "real" vector bundles of higher rank have a trivial summand and such that a stable isomorphism for such bundles implies ordinary isomorphism. We…

Many-body Expansion Based Machine Learning Models for Octahedral Transition Metal Complexes Open
Graph-based machine learning models for materials properties show great potential to accelerate virtual high-throughput screening of large chemical spaces. However, in their simplest forms, graph-based models do not include any 3D informat…

A universal coefficient theorem for actions of finite groups on C*-algebras Open
The equivariant bootstrap class in the Kasparov category of actions of a finite group G consists of those actions that are equivalent to one on a Type I C*-algebra. Using a result by Arano and Kubota, we show that this bootstrap class is a…

Correspondences between graph C*-algebras Open
We describe proper correspondences from graph C*-algebras to arbitrary C*-algebras by K-theoretic data. If the target C*-algebra is a graph C*-algebra as well, we may lift an isomorphism on a certain invariant to correspondences back and f…

Analytic cyclic homology in positive characteristic Open
Let $V$ be a complete discrete valuation ring with residue field\n$\\mathbb{F}$. We define a cyclic homology theory for algebras over\n$\\mathbb{F}$, by lifting them to free algebras over $V$, which we enlarge to\ntube algebras and complet…

Inductive limits of noncommutative Cartan inclusions Open
We prove that an inductive limit of aperiodic noncommutative Cartan inclusions is a noncommutative Cartan inclusion whenever the connecting maps are injective, preserve normalisers and entwine conditional expectations. We show that under t…

Significantly longer time to deterioration of quality of life due to CANKADO PRO-React eHealth support in HR+ HER2− metastatic breast cancer patients receiving palbociclib and endocrine therapy: primary outcome analysis of the multicenter randomized AGO-B WSG PreCycle trial Open
PreCycle is the first multicenter randomized eHealth trial demonstrating a significant benefit for MBC patients receiving oral tumor therapy when using an interactive autonomous patient empowerment application.

Geometric construction of classes in van Daele’s K-theory Open
We describe explicit generators for the “real” K-theory of “real” spheres in van Daele’s picture. Pulling these generators back along suitable maps from tori to spheres produces a family of Hamiltonians used in the physics literature on to…

A Transferable Recommender Approach for Selecting the Best Density Functional Approximations in Chemical Discovery Open
Approximate density functional theory (DFT) has become indispensable owing to its cost-accuracy trade-off in comparison to more computationally demanding but accurate correlated wavefunction theory. To date, however, no single density func…
