Seventy-second meeting of the Transpennine Topology Triangle



Department of Pure Mathematics
University of Sheffield
Tuesday
02/02/10


This will be a working meeting. There will therefore be the usual time for participant discussion.


Programme


We expect to go to eat nearby, soon after the last talk.

Abstracts

Justin Noel "For orientations preserving power operations, p-typicality is atypical."

In joint work with Niles Johnson, we have computed some obstructions for an H_\infty complex orientation to factor through the Brown-Peterson spectrum. The non-triviality of these obstructions show that a number of standard ring spectra maps MU-->E, can not be maps of E_\infty ring spectra. Examples include E=BP, E_n, and E(n) for n>0 and p<7.


Anyone who wishes to participate is welcome: we shall operate the usual arrangements for assistance with travel expenses. We expect to assemble for tea and coffee in I15, Floor 5, from 11.00 am until the first talk. Each lecture will take place in Room J11 of the Hicks Building, Hounsfield Road, Sheffield.
Tea and Coffee will be served in the common room I15.
For further information email John Greenlees j.greenlees@sheffield.ac.uk, (or John Hunton jrh7@mcs.le.ac.uk or Nige Ray nige@ma.man.ac.uk) if you are interested, so we can make approximately the right amount of tea and coffee.


How to get there

From the rail station, you can catch the Number 40 bus (Orange Line), and get off where it crosses the ring road. Or take the supertram to the University stop. There is more information at School of Mathematics and Statistics Homepage
The meeting is partially supported by a Scheme 3 grant from the London Mathematical Society.
