Hodge-Elliptic genera, K3 surfaces and Enumerative Geometry
Michele Cirafici
K3 surfaces play a prominent role in string theory and algebraic geometry. The properties of their enumerative invariants have important consequences in black hole physics and in n…
On the M2-Brane Index on Noncommutative Crepant Resolutions
Michele Cirafici
On certain M-theory backgrounds which are a circle fibration over a smooth Calabi-Yau, the quantum theory of M2 branes can be studied in terms of the K-theoretic Donaldson-Thomas t…
A note on discrete dynamical systems in theories of class
Michele Cirafici
In this note we consider the set of line operators in theories of class . We show that this set carries the action of a natural discrete dynamical system associated with the BPS…
Quantum Line Defects and Refined BPS Spectra
Michele Cirafici
In this note we study refined BPS invariants associated with certain quantum line defects in quantum field theories of class . Such defects can be specified via geomet…
On Framed Quivers, BPS Invariants and Defects
Michele Cirafici
In this note we review some of the uses of framed quivers to study BPS invariants of Donaldson-Thomas type. We will mostly focus on non-compact Calabi-Yau threefolds. In certain ca…
Quivers, Line Defects and Framed BPS Invariants
Michele Cirafici
A large class of N=2 quantum field theories admits a BPS quiver description and the study of their BPS spectra is then reduced to a representation theory problem. In such theories…
