Serre's conjecture on projective modules over polynomial rings
Young, Edward ; Shaul, Liran (advisor) ; Bird, Isaac (referee)
This is an expository paper on the Quillen-Suslin Theorem, formerly known as Serre's Conjecture. A self-contained proof of this theorem is presented, followed by a discussion of the related Bass-Quillen Conjecture. The first chapter establishes the necessary theory, building on undergraduate algebra with the essentials of free, projective, and flat modules. The second chapter presents a complete proof of the theorem, dealing with regular rings, stably-free modules, and the related calculus of unimodular rows. The third and final chapter lists partial results surrounding the as yet unresolved Bass-Quillen Conjecture, offering brief explanations and suggestions for further reading. 1
Cohen-Macaulay modules over simple singularities
Zhang, Yifan ; Šťovíček, Jan (advisor) ; Bird, Isaac (referee)
The thesis is focused on the maximal Cohen-Macaulay modules over simple singular- ities. Previous results on the topic are summarised, and in particular it is shown that a hypersurface is MCM-finite if and only if it is a simple singularity. The stable Auslander- Reiten quivers of simple singularities are drawn for better understanding of the category of maximal Cohen-Macaulay modules over a simple singularity. 1
