Categories of Massless D-Branes and del Pezzo Surfaces
Nicolas Addington, Paul S. Aspinwall
In analogy with the physical concept of a massless D-brane, we define a notion of "Q-masslessness" for objects in the derived category. This is defined in terms of monodromy around…

D-brane probes, branched double covers, and noncommutative resolutions
Nicolas Addington, Edward Segal, Eric Sharpe
This paper describes D-brane probes of theories arising in abelian gauged linear sigma models (GLSMs) describing branched double covers and noncommutative resolutions thereof, via…
