Brief Description:
Special Note:
Abstract:
The celebrated prismatic cohomology is seen as a universal p-adic cohomology theory. In a similar vein, a particular piece of torsion inside prismatic cohomology can be seen as a universal pathology. I shall state a guess about this piece of torsion. Then I will motivate it via some numerical “coincidence” with the J-homomorphism in topology, as well as computing an explicit example. It’s a joint work with Tong Liu.Date: Wednesday, April 13, 2022
