Comparing the face rings of a boolean complex and its barycentric subdivision
Ben Blum-Smith, Sophie Marques
We consider the relationship between the Stanley--Reisner ring (a.k.a. face ring) of a simplicial or boolean complex and that of its barycentric subdivision. These rings share…

Two inquiries about finite groups and well-behaved quotients
Ben Blum-Smith
This thesis addresses questions in representation and invariant theory of finite groups. The first concerns singularities of quotient spaces under actions of finite groups. We intr…

When are permutation invariants Cohen-Macaulay over all fields?
Ben Blum-Smith, Sophie Marques
We prove that the polynomial invariants of a permutation group are Cohen-Macaulay for any choice of coefficient field if and only if the group is generated by transpositions, doubl…
