Coarsenings, injectives and Hom functors
Fred Rohrer
It is characterized when coarsening functors between categories of graded modules preserve injectivity of objects, and when they commute with graded covariant Hom functors.

Coarsening of graded local cohomology
Fred Rohrer
Some criteria for graded local cohomology to commute with coarsening functors are proven, and an example is given where graded local cohomology does not commute with coarsening.

Torsion functors with monomial support
Fred Rohrer
The dependence of torsion functors on their supporting ideals is investigated, especially in the case of monomial ideals of certain subrings of polynomial algebras over not necessa…
