The universal sl(2) cohomology via webs and foams
Carmen Caprau
We construct the universal sl(2)-tangle cohomology using an approach with webs and dotted foams. This theory depends on two parameters, and for the case of links it is a categorifi…

An sl(2) tangle homology and seamed cobordisms
Carmen Caprau
We construct a bigraded (co)homology theory which depends on a parameter a, and whose graded Euler characteristic is the quantum sl(2) link invariant. We follow Bar-Natan's approac…
