DESCRIPTION:Title: Immersed curves in Khovanov homology\n\nAbstract: Consid
 er a 2-sphere S intersecting a knot K in 4 points. This defines decomposit
 ion of a knot into two 4-ended tangles. We will show that Khovanov homolog
 y Kh(K)\, and its deformation due to Bar-Natan\, are isomorphic to Lagrang
 ian Floer homology of a pair of specifically constructed immersed curves o
 n the dividing 4-punctured sphere S. This result is analogous to immersed 
 curves description of bordered Heegaard Floer homology and knot Floer homo
 logy. The key step will be constructing a tangle invariant in the form of 
 a chain complex over a certain algebra B (deformation of Khovanov's arc al
 gebra)\, and showing that algebra B embeds in a nice way into the wrapped 
 Fukaya category of the 4-punctured sphere Fuk(S). As an application\, we w
 ill prove that Conway mutation preserves Rasmussen's s-invariant of knots.
 \n	This is joint work with Liam Watson and Claudius Zibrowius.\n
