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

further information email John Greenlees j.greenlees@sheffield.ac.uk, (or

so we can make approximately the right amount of tea and coffee.
