Query: D-branes, surface operators, and ADHM quiver representations   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 represents the effective action of a certain D2-brane
configuration, and is naturally obtained by dimensional reduction of a quiver
$(0,2)$ gauged linear sigma model. In a special stability chamber, the
resulting moduli space of quiver representations is shown to be virtually
smooth and isomorphic to a moduli space of framed quotients on the projective
plane. A precise conjecture relating a K-theoretic partition function of this
moduli space to refined open string invariants of toric lagrangian branes is
formulated for conifold and local P^1 x P^1 geometries.
