Invariants of nested Hilbert and Quot schemes on surfaces
Nadir Fasola, Michele Graffeo, Danilo Lewański +1
Let be a smooth pointed surface. In the first part of this paper we study motivic invariants of punctual nested Hilbert schemes attached to using the Hilbert-Samuel…
Tetrahedron instantons in Donaldson-Thomas theory
Nadir Fasola, Sergej Monavari
Inspired by the work of Pomoni-Yan-Zhang in String Theory, we introduce the moduli space of tetrahedron instantons as a Quot scheme and describe it as a moduli space of quiver repr…
ADHM in 8d, coloured solid partitions and Donaldson-Thomas invariants on orbifolds
Giulio Bonelli, Nadir Fasola, Alessandro Tanzini +1
We study the moduli space of invariant BPS conditions in supersymmetric gauge theory on non-commutative by means of an ADHM-like quiver construction and we…
Higher rank K-theoretic Donaldson-Thomas theory of points
Nadir Fasola, Sergej Monavari, Andrea T. Ricolfi
We exploit the critical locus structure on the Quot scheme , in particular the associated symmetric obstruction theory, in ord…
Flags of sheaves, quivers and symmetric polynomials
Giulio Bonelli, Nadir Fasola, Alessandro Tanzini
We study the representation theory of the nested instantons quiver presented in [1], which describes a particular class of surface defects in four-dimensional supersymmetric gauge…
Defects, nested instantons and comet shaped quivers
Giulio Bonelli, Nadir Fasola, Alessandro Tanzini
We introduce and study a surface defect in four dimensional gauge theories supporting nested instantons with respect to the parabolic reduction of the gauge group at the defect. Th…
