Young Modules and Schur algebras Open
We compute explicitly the submodule structure of the Young modules for symmetric groups $S_n$ over fields of characteristic 2, when $n \le 7$. We use this information to compute the submodule structure of indecomposable projectives for the…

Shipping Container Chassis in the U. S. Open
The University of New Orleans Transportation Institute (UNOTI) examined the issues surrounding the current state of international chassis utilization in the United States (U.S.). The international chassis system in the U.S. is unique compa…

The bounded derived category of a poset Open
We introduce a new combinatorial condition on a subinterval of a poset P (a clamped subinterval) that allows us to relate the Auslander-Reiten quiver of the bounded derived category of P to that of the subinterval. Applications include the…

THE GRADED CENTER OF A TRIANGULATED CATEGORY Open
With applications in mind to the representations and cohomology of block algebras, we examine elements of the graded center of a triangulated category when the category has a Serre functor. These are natural transformations from the identi…

On the projective dimensions of Mackey functors Open
We examine the projective dimensions of Mackey functors and cohomological Mackey functors. We show over a field of characteristic $p$ that cohomological Mackey functors are Gorenstein if and only if Sylow $p$-subgroups are cyclic or dihedr…
