Generating invariant rings of quivers in arbitrary characteristic
Harm Derksen, Visu Makam
It is well known that the ring of polynomial invariants of a reductive group is finitely generated. However, it is difficult to give strong upper bounds on the degrees of the gener…

On non-commutative rank and tensor rank
Harm Derksen, Visu Makam
We study the relationship between the commutative and the non-commutative rank of a linear matrix. We give examples that show that the ratio of the two ranks comes arbitrarily clos…

Degree bounds for semi-invariant rings of quivers
Harm Derksen, Visu Makam
We use recent results on matrix semi-invariants to give degree bounds on generators for the ring of semi-invariants for quivers with no oriented cycles.
