<p></p> <p><b>New page</b></p><div>{{KAL/Navigation}}<br /> <br /> ==Invitation==<br /> <br /> Dear Knot at Lunch People,<br /> <br /> We will have our next lunch on Wednesday March 5, at the usual place, Bahen 6180, at 12 noon.<br /> <br /> As always, please bring brown-bag lunch and fresh ideas. The agenda: Krzysztof Putyra may tell us about the Odd Khovanov Homology following {{arXiv|0710.4300}}, or we may talk about something else.<br /> <br /> Further information about this meeting will/may appear at &lt;span class=&quot;plainlinks&quot;&gt;{{SERVER}}/drorbn/index.php?title={{PAGENAMEE}}&lt;/span&gt;.<br /> <br /> As always, if you know anyone I should add to this mailing list or if you wish to be removed from this mailing list please let me know. To prevent junk accumulation in mailboxes, I will actively remove inactive people unless they request otherwise.<br /> <br /> Best,<br /> <br /> Dror.<br /> <br /> ==Some Content==<br /> <br /> * Picture of Khovanov construction<br /> * 1+1 cobordisms and TQFT<br /> * Odd homologies by Rasmussen and Ozsvath - differences with Khovanov theory<br /> * Cobordisms with chronologies<br /> * Conditions on changing chronology to get a complex<br /> * How many link homology theories exists?<br /> <br /> I (Krzysztof) will start with the original construction of Khovanov and a TQFT functor.<br /> Then describe the construction of Rasmussen and Ozsvath by showing the<br /> differences with the previous one. In this way I will show why chronology is<br /> natural for this construction and why we want linear relations for changing<br /> it. I&#039;m going to do here some examples rather than all calculations. The<br /> last one is still an open question as I haven&#039;t found yet any new<br /> non-trivial theories, so the answer is 2-8.</div>
