The log symplectic geometry of Poisson slices
Peter Crooks, Markus Röser
Our paper develops a theory of Poisson slices and a uniform approach to their partial compactifications. The theory in question is loosely comparable to that of symplectic cross-se…

Hessenberg varieties and Poisson slices
Peter Crooks, Markus Röser
This work pursues a circle of Lie-theoretic ideas involving Hessenberg varieties, Poisson geometry, and wonderful compactifications. In more detail, one may associate a symplectic…
