Lower bound for ranks of invariant forms
Harm Derksen, Zach Teitler
We give a lower bound for the Waring rank and cactus rank of forms that are invariant under an action of a connected algebraic group. We use this to improve the Ranestad--Schreyer-…

Geometric lower bounds for generalized ranks
Zach Teitler
We revisit a geometric lower bound for Waring rank of polynomials (symmetric rank of symmetric tensors) of Landsberg and Teitler and generalize it to a lower bound for rank with re…

On Maximum, Typical and Generic Ranks
Grigoriy Blekherman, Zach Teitler
We show that for several notions of rank including tensor rank, Waring rank, and generalized rank with respect to a projective variety, the maximum value of rank is at most twice t…
