SUMMARY:Link cobordisms\, configuration spaces and a more natural setting

DESCRIPTION:The Jones polynomial of links is still not naturally defined a
 nd not\nproperly geometrically understood. Khovanov's categorification of 
 the Jones\npolynomial relates it to the geometry of smooth surfaces in 4D\
 , but is also\npoorly geometrically understood. One attempt at fixing this
  is the so called\n'symplectic Khovanov homology'\, which has nicer geomet
 ric properties and is\nconjectured to be isomorphic to Khovanov homology. 
 I shall explain how\nobservations about the geometry of configuration spac
 es give us a first step\nin proving this conjecture and also allow symplec
 tic Khovanov homology to be\nmore naturally presented for links and tangle
