Vector fields and admissible embeddings for quiver moduli
Pieter Belmans, Ana-Maria Brecan, Hans Franzen +1
We introduce a double framing construction for moduli spaces of quiver representations. It allows us to reduce certain sheaf cohomology computations involving the universal represe…
Rigidity and Schofield's partial tilting conjecture for quiver moduli
Pieter Belmans, Ana-Maria Brecan, Hans Franzen +2
We explain how Teleman quantization can be applied to moduli spaces of quiver representations to compute the higher cohomology of the endomorphism bundle of the universal bundle. W…
Torus Actions on Quotients of Affine Spaces
Ana-Maria Brecan, Hans Franzen
We study the locus of fixed points of a torus action on a GIT quotient of a complex vector space by a reductive complex algebraic group which acts linearly. We show that, under the…
Unobstructedness of hyperkähler twistor spaces
Ana-Maria Brecan, Tim Kirschner, Martin Schwald
A family of irreducible holomorphic symplectic (ihs) manifolds over the complex projective line has unobstructed deformations if its period map is an embedding. This applies in par…
Cycle transversal flag domains of Hodge type
Ana-Maria Brecan
Flag domains are open orbits of real semisimple Lie groups in flag manifolds of their complexification. A special class of flag domains constitute the classifying spaces for variat…
Schubert slices in the combinatorial geometry of flag domains
Ana-Maria Brecan
Flag domains are open orbits of real semisimple Lie groups in flag manifolds of their complexifications. Certain group theoretically defined compact complex submanifolds, which are…
Schubert duality for SL(n,R)-flag domains
Ana-Maria Brecan
This paper is concerned with the study of spaces of naturally defined cycles associated to SL(n,R)-flag domains. These are compact complex submanifolds in open orbits of real semis…
