MSc presentation
Stan Wever - The Unoriented Cobordism Ring

Supervisor: Dr. Gijs Heuts

Second Reader: Dr. Lennart Meier

Abstract: Inmy thesis, I gave a purely algebraic description of the unoriented cobordismring. This description is based on the important work of Thom, which showedthat there exist isomorphisms between cobordism rings and Thom spectra. Thisgives the possibility to move this problem in differential topology intoalgebraic topology, in which we have an abundance of tools to makecalculations. Within my presentation, I will take the time to define theunoriented cobordism ring, outline its calculation and give a set ofgenerators. Most of the presentation will be spent on constructing thePontrjagin-Thom construction, which gives the before-mentionedisomorphism. 

Forthis talk, it is convenient to be familiar with some algebraic topology, but itis not necessary.
