Motivic and cohomological stabilisation of the Quot scheme of points

Michele Graffeo, Sergej Monavari, Riccardo Moschetti +1

We prove that the motive of the punctual Quot scheme stabilises, when , to $[\mathrm{Gr}(d-1,\infty)]\cdot \s…

Derived hyperquot schemes

Sergej Monavari, Emanuele Pavia, Andrea T. Ricolfi

We define a derived enhancement of the hyperquot scheme (also known as nested Quot scheme), which classically parametrises flags of quotients of a perfect coherent sheaf on a proje…

Moduli spaces of semiorthogonal decompositions in families

Pieter Belmans, Shinnosuke Okawa, Andrea T. Ricolfi

To a smooth and proper morphism with quasicompact semiseparated target we associate a sheaf in the étale topology, which takes an affine -scheme to the s…

Deformation theory for a morphism in the derived category with fixed lift of the codomain

Pieter Belmans, Wendy Lowen, Shinnosuke Okawa +1

We develop the deformation-obstruction calculus for morphisms of complexes with a fixed lift of the codomain, to derived categories of flat nilpotent deformations of abelian catego…

Indecomposability of derived categories in families

Francesco Bastianelli, Pieter Belmans, Shinnosuke Okawa +1

Using the moduli space of semiorthogonal decompositions in a smooth projective family, introduced by the second, the third and the fourth author, we propose a novel approach to ind…

On the stack of 0-dimensional coherent sheaves: motivic aspects

Barbara Fantechi, Andrea T. Ricolfi

Let be a variety. In this survey, we study (decompositions of) the motivic class, in the Grothendieck ring of stacks, of the stack of -dimensional coher…
