Knot Homologies and BPS States: April 22-April 28, 2012

Date & Time


In recent years, homological knot invariants have been gaining momentum in both mathematics and physics, and recent developments promise it will only be growing. Therefore, a symposium on “the physics of knot homologies” is very timely.

Moreover, this subject is intimately connected with another active area of research at the interface of geometry and physics: the study of BPS invariants and their behavior under wall crossing. The relation between quantum invariants of knots and 3-manifolds on one hand, and wall crossing of refined BPS invariants on the other, is currently a very active area of research. The underlying reason for this interesting connection is that, in a physical realization of knot homologies as spaces of BPS states, the basic operations in knot theory (such as skein relations) correspond to changes of the (brane) system under which the spectrum of BPS states jumps.
