Khovanov homology is an invariant of oriented links, that is defined
as the cohomology of a chain complex built from the cube of
resolutions of a link diagram. Discovered in the late 90s, it is the
first of, and inspiration for, a series of "categorifications" of knot
invariants. In this first of two one-hour talks, I'll give some
background on categorification and the Jones polynomial,
defineKhovanov homology, work through some examples, and give a
portion of the proof of Reidemeister invariance.
