Michi’s blog » Going to T’bilisi
Going to T’bilisiIn about 23 hours, I’ll step on to the train in Jena, heading for T’bilisi, Georgia.
On Monday, I’ll give a talk on my research into 
-structures in group cohomology. If you’re curious, I already put the slides up on the web.
I’ll try to blog from T’bilisi, but I don’t know what connectivity I’ll have at all.
John: I’m glad you read the slides. Thanks for the example and the comment – but I don’t think it essentially changes my argument, namely that a na�ve approach to lifting the restriction maps from cohomology to the Aoo-structures seems doomed from the start.
The actual talk went very well, and I’m enjoying a sunny and very hot T’bilisi right now.

I’m about a week too late, but I don’t agree with your statement on p. 16 of the notes that if H is a subgroup of G, then the induced map on cohomology is surjective. (Consider C_2 inside C_4.) Maybe the lack of surjectivity makes it easier to understand the induced map of A-infinity algebras?
