Simplicity criteria for etale groupoid -algebras
Danny Crytser, Gabriel Nagy
We develop a framework suitable for obtaining simplicity criteria for reduced -algebras of Hausdorff etale groupoids. This is based on the study of certain non-degenerate $C^*…
Traces arising from regular inclusions
Danny Crytser, Gabriel Nagy
We study the problem of extending a state on an abelian - subalgebra to a tracial state on the ambient -algebra. We propose an approach that is well-suited to the case of…
Pseudo-Diagonals and Uniqueness Theorems
Gabriel Nagy, Sarah Reznikoff
We examine a certain type of abelian C*-subalgebras that allow one to give a unified treatment of two uniqueness theorems: for graph C*-algebras and for certain reduced crossed pro…
A generalized Cuntz-Krieger uniqueness theorem for higher rank graphs
Jonathan H. Brown, Gabriel Nagy, Sarah Reznikoff
We present a uniqueness theorem for k-graph C*-algebras that requires neither an aperiodicity nor a gauge invariance assumption. Specifically, we prove that for the injectivity of…
Rough solutions of the Einstein constraints on closed manifolds without near-CMC conditions
Michael Holst, Gabriel Nagy, Gantumur Tsogtgerel
We consider the conformal decomposition of Einstein's constraint equations introduced by Lichnerowicz and York, on a closed manifold. We establish existence of non-CMC weak solutio…
Rough solutions of the Einstein constraint equations with nonconstant mean curvature
M. Holst, J. Kommemi, G. Nagy
We consider the conformal decomposition of Einstein's constraint equations introduced by Lichnerowicz and York, on a compact manifold with boundary. We use order relations on appro…
