Koszul complexes and spectral sequences associated with Lie algebroids

U. Bruzzo, V. N. Rubtsov

We study some spectral sequences associated with a locally free $O_{X}$ -module $A$ which has a Lie algebroid structure. Here $X$ is either a complex manifold or a r…

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 $S U (4)$ invariant BPS conditions in supersymmetric gauge theory on non-commutative $C^{4}$ by means of an ADHM-like quiver construction and we…

A note on discrete dynamical systems in theories of class $S$

Michele Cirafici

In this note we consider the set of line operators in theories of class $S$ . We show that this set carries the action of a natural discrete dynamical system associated with the BPS…

Isomonodromic tau functions on a torus as Fredholm determinants, and charged partitions

Fabrizio Del Monte, Harini Desiraju, Pavlo Gavrylenko

We prove that the isomonodromic tau function on a torus with Fuchsian singularities and generic monodromies in $G L (N, C)$ can be written in terms of a Fredholm determinant…

BPS quivers of five-dimensional SCFTs, Topological Strings and q-Painlevé equations

Giulio Bonelli, Fabrizio Del Monte, Alessandro Tanzini

We study the discrete flows generated by the symmetry group of the BPS quivers for Calabi-Yau geometries describing five dimensional superconformal quantum field theories on a circ…

Codimension bounds for the Noether-Lefschetz components for toric varieties

Ugo Bruzzo, William D. Montoya

For a quasi-smooth hyper-surface $X$ in a projective simplicial toric variety $P$ , the morphism $i : H^{p} (P) \to H^{p} (X)$ induced by the inclusion is injective for $p = d$ and an isomorp…

Levi-Civita connections and vector fields for noncommutative differential calculi

Jyotishman Bhowmick, Debashish Goswami, Giovanni Landi

We study covariant derivatives on a class of centered bimodules $E$ over an algebra A. We begin by identifying a $Z (A)$ -submodule $X (A)$ which…
