Partial compactification of stability manifolds via massless semistable objects

Nathan Broomhead, David Pauksztello, David Ploog +1

We introduce two extensions of the space of Bridgeland stability conditions of a triangulated category. First we consider lax stability conditions where semistable objects are allo…

Mass-growth of triangulated auto-equivalences

Jon Woolf

We relate the mass growth (with respect to a stability condition) of an exact auto-equivalence of a triangulated category to the dynamical behaviour of its action on the space of s…

Perverse sheaves and finite-dimensional algebras

Alessio Cipriani, Jon Woolf

Let be a topologically stratified space, be any perversity on , and be a field. We show that the category of -perverse sheaves on , constructible with respect…

Witt groups of abelian categories and perverse sheaves

Jörg Schürmann, Jon Woolf

In this paper we study the Witt groups of symmetric and anti-symmetric forms on perverse sheaves on a finite-dimensional topologically stratified space with even dimensional strata…

Surjectivity of the hyperkähler Kirwan map

Jonathan Fisher, Lisa Jeffrey, Young-Hoon Kiem +2

We study a class of group actions on hyperkähler manifolds which we call actions of linear type. If is a hyperkähler manifold possessing such a -action, the hyperkähler Kirw…

Contractible stability spaces and faithful braid group actions

Yu Qiu, Jon Woolf

We prove that any `finite-type' component of a stability space of a triangulated category is contractible. The motivating example of such a component is the stability space of the…
