BPS states and the P=W conjecture
W. -Y. Chuang, D. -E. Diaconescu, G. Pan
A string theoretic framework is presented for the work of Hausel and Rodriguez-Vilegas as well as de Cataldo, Hausel and Migliorini on the cohomology of character varieties. The ce…
D-branes, surface operators, and ADHM quiver representations
U. Bruzzo, W. -y. Chuang, D. -E. Diaconescu +3
A supersymmetric quantum mechanical model is constructed for BPS states bound to surface operators in five dimensional SU(r) gauge theories using D-brane engineering. This model re…
Wallcrossing and Cohomology of The Moduli Space of Hitchin Pairs
Wu-yen Chuang, Duiliu-Emanuel Diaconescu, Guang Pan
A conjectural recursive relation for the Poincaré polynomial of the Hitchin moduli space is derived from wallcrossing in the refined local Donaldson-Thomas theory of a curve. A dou…
Rank Two ADHM Invariants and Wallcrossing
Wu-yen Chuang, Duiliu-Emanuel Diaconescu, Guang Pan
Generalized Donaldson-Thomas invariants corresponding to local D6-D2-D0 configurations are defined applying the formalism of Joyce and Song to ADHM sheaves on curves. A wallcrossin…
Chamber Structure and Wallcrossing in the ADHM Theory of Curves II
Wu-yen Chuang, Duiliu-Emanuel Diaconescu, Guang Pan
This is the second part of a project concerning variation of stability and chamber structure for ADHM invariants of curves. Wallcrossing formulas for such invariants are derived us…
BPS State Counting in Local Obstructed Curves from Quiver Theory and Seiberg Duality
Wu-yen Chuang, Guang Pan
In this paper we study the BPS state counting in the geometry of local obstructed curve with normal bundle O+O(-2). We find that the BPS states have a framed quiver description. Us…
