Hi folks,
The last SGGTC seminar of the semester is on Friday, at 10:45, in MATH 312 (because of exams). Andras Stipsicz is speaking.
Friday, May 4, 10:45 a.m. in Math 312.
Andras Stipsicz, "Knots in Lattice homology"
Abstract: In 2008 Nemethi introduced an invariant of negative definite plumbings, called lattice homology. We introduce a filtration on the lattice homology of a negative definite plumbing tree associated to a further vertex and show how to determine lattice homologies of surgeries on this last vertex. We discuss the relation with Heegaard Floer homology.
Andras gives great talks; I highly recommend it. We'll head to lunch after the talk, as usual.
Best,
Robert
