Surfaces with pulleys and Khovanov homology
Résumé
In this short note, we define surfaces with pulleys which are unions of 1 and 2-dimensional manifolds, glued together on a finite number of points of their interiors. Then, by seeing them as cobordisms, we give a refinment of Bar-Natan geometrical construction of Khovanov homology which can be applied to different notions of refined links as links in I-bundle or braid-like links.
