Invariants of the finite orthogonal groups in odd dimension and even characteristic
H. E. A. Campbell, R. J. Shank, D. L. Wehlau
We describe the ring of invariants for the finite orthogonal groups in odd dimension and even characteristic acting on the defining representation. We construct a minimal algebra g…
Invariants of Finite Orthogonal Groups of Plus Type in Odd Characteristic
H. E. A. Campbell, R. James Shank, David L. Wehlau
We describe the rings of invariants for the finite orthogonal groups of plus type in odd characteristic acting on the defining representations. We also describe the invariants of t…
When are permutation invariants Cohen-Macaulay?
H. E. A. Campbell, David L. Wehlau
Over a field of characteristic 0, every ring of invariants of a finite group is Cohen-Macaulay. This is not true for fields of positive characteristic. We consider permutation repr…
Semi-Invariant Rings: UFD and Codimension One Orbits
Charles Paquette, Deepanshu Prasad, David Wehlau
Let be a finite dimensional associative -algebra over an algebraically closed field of characteristic zero. To , we can associate its basic form tha…
Representations of free products of semisimple algebras via quivers
Andrew Buchanan, Ivan Dimitrov, Olivia Grace +3
Let denote an algebraically closed field and a free product of finitely many semisimple associative -algebras. We associate to a finite acyclic qui…
Ten Points on a Cubic
Will Traves, David Wehlau
The 16-year old Blaise Pascal found a way to determine if 6 points lie on a conic using a straightedge. Nearly 400 years later, we develop a method that uses a straightedge to chec…
