I'm just about to start my final year of undergrad. I need to choose a thesis title but I'm having some trouble. I know a little Galois Cohomology and would really like to learn more. The prof who is supervising me said he is not keen on me doing a project on Galois cohomology because it is 'just a tool'.
Is this true?
Any suggestions for a thesis title which will allow me to learn Galois cohomology while not being totally direction-less; a project which has a 'direction'?
