Orthogonal Intertwiners for Infinite Particle Systems in The Continuum
Stefan Wagner
This article focuses on a system of sticky Brownian motions, also known as Howitt-Warren martingale problem, and correlated Brownian motions and shows that infinite-dimensional ort…
The noncommutative geometry of frame bundles
Stefan Wagner
We apply ourselves to the noncommutative geometry of frame bundles by showing that each C-algebraic noncommutative principal -bundle is, up to isomorphism, uniq…
Non-Abelian extensions of groupoids and their groupoid rings
Natã Machado, Johan Öinert, Stefan Wagner
We present a geometrically oriented classification theory for non-Abelian extensions of groupoids generalizing the classification theory for Abelian extensions of groupoids by West…
Intertwining and Duality for Consistent Markov Processes
Simone Floreani, Sabine Jansen, Frank Redig +1
In this paper we derive intertwining relations for a broad class of conservative particle systems both in discrete and continuous setting. Using the language of point process theor…
An Atiyah Sequence for Noncommutative Principal Bundles
Kay Schwieger, Stefan Wagner
We present a derivation-based Atiyah sequence for noncommutative principal bundles. Along the way we treat the problem of deciding when a given -automorphism on the quantum bas…
Prime group graded rings with applications to partial crossed products and Leavitt path algebras
Daniel Lännström, Patrik Lundström, Johan Öinert +1
In this article we generalize a classical result by Passman on primeness of unital strongly group graded rings to the class of nearly epsilon-strongly group graded rings which are…
