Punctual noncommutative Hilbert schemes
Markus Reineke
Punctual noncommutative Hilbert schemes are projective varieties parametrizing finite codimensional left ideals in noncommutative formal power series rings. We determine their moti…

Local intersection cohomology of varieties of complexes
Xin Fang, Markus Reineke
We compute the local intersection cohomology of the irreducible components of varieties of complexes, by using Lusztig's geometric approach to quantum groups and explicit construct…

Motives of central slope Kronecker moduli
Alexandre Astruc, Frederic Chapoton, Karen Martinez +1
We use dualities of quiver moduli induced by reflection functors to describe generating series of motives of Kronecker moduli spaces of central slope as solutions of algebraic and…
