Kervaire invariant seminar
This is the webpage for the seminar on the Kervaire invariant one problem. Before the summer, we treated some of the historical background on this problem, see here. This semester, the autumn of 2019, we will have weekly meetings where we study the solution to this problem by Mike Hill, Mike Hopkins and Douglas Ravenel.
PhD students from SU or KTH can receive 7.5 ECTS for participating. The syllabus, which includes the requirements for receiving credits, can be found here.
