On Khovanov's categorification of the Jones polynomial
The working mathematician fears complicated words but loves pictures and
diagrams. We thus give a no-fancy-anything picture rich glimpse into Khovanov's
novel construction of `the categorification of the Jones polynomial'. For the
same low cost we also provide some computations, including one that shows that
Khovanov's invariant is strictly stronger than the Jones polynomial and
including a table of the values of Khovanov's invariant for all prime knots
with up to 11 crossings.Comment: Published by Algebraic and Geometric Topology at

Categorification of the colored -invariant
We give explicit resolutions of all finite dimensional, simple
-modules. We use these resolutions to categorify the
colored -invariant of framed links via a complex of complexes
of graded -modules.Comment: 39 pages, many figures. Comments welcome
