Abstract:   This lecture will be about the physics and geometry of new knot invariants invented by Khovanov, Rozansky, Ozsvath, Szabo, Rasmussen, and other mathematicians circa 2000. The key ingredients of the proposed physical framework involve standard tools from gauge theory and string theory. It leads to a wealth of generalizations and comes with a few surprising features ...

Here are some directions to Northeastern University. Lake Hall and Nightingale Hall can be best accessed from the entrance on the corner of Greenleaf Street and Leon Street. The two halls are connected, with no well-defined boundary in between. In particular, 509 Lake Hall is on the same corridor as 544 Nightingale Hall.
