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…
Modular invariants of finite gluing groups
Yin Chen, R. James Shank, David L. Wehlau
We use the gluing construction introduced by Jia Huang to explore the rings of invariants for a range of modular representations. We construct generating sets for the rings of inva…
On invariant fields of vectors and covectors
Yin Chen, David L. Wehlau
Let be the finite field of order . Let be one of the three groups , or a…
Degrees of regular sequences with a symmetric group action
Federico Galetto, Anthony V. Geramita, David L. Wehlau
We consider ideals in a polynomial ring that are generated by regular sequences of homogeneous polynomials and are stable under the action of the symmetric group permuting the vari…
