 Blogging seminars – a new fad!

They simply do not end. Now, Cornell grads and pre-grads have started the Everything Seminar – which has absolutely brilliant discussions about the forbidden minor theorem in graph theory as well as a fascinating overview over constructing homological algebra as embedded in the theory of modules over \mathbb C[\epsilon]=\mathbb C[x]/(x^2).

Connected to this comes the observation that by constructing calculus using the tricks used in synthetic differential geometry, we end up with – again – modules over \mathbb C[\epsilon], and some very fascinating discussions are sparked as to subtle and interesting connections between these two viewpoints!

How on earth I am going to keep up with the interesting sprouting discussion group blogs I shall never know. Maybe it’s getting to the point where we’ll start an A_\infty-blog?

3 People had this to say...


I heartily support the idea of an [tex]A_\infty[/tex] blog. One direction I still haven’t written about for my [tex]\mathbb{C}[\epsilon][/tex] posts was about enriching categories over [tex]\mathbb{C}[\epsilon]-\mathbf{mod}[/tex], which with the superalgebra structure can be turned into the notion of a dg-category.

Please, please, please do an A_\infty blog.

Palen: It doesn’t seem impossible to get something like that up and running. I’m hearing good noises in the nearest community, just haven’t gotten around to kickstart something quite yet.

Want your say?
