Distinguishing secant from cactus varieties [PDF]

arXiv, 2020
Cactus varieties are a generalization of secant varieties. They are defined using linear spans of arbitrary finite schemes of bounded length, while secant varieties use only isolated reduced points. In particular, any secant variety is always contained in the respective cactus variety, and, except in a few initial cases, the inclusion is strict.

New examples of defective secant varieties of Segre-Veronese varieties [PDF]

Collectanea Mathematica. 63, (2012) 3, 287-297, 2011
We prove the existence of defective secant varieties of three-factor and four-factor Segre-Veronese varieties embedded in certain multi-degree. These defective secant varieties were previously unknown and are of importance in the classification of defective secant varieties of Segre-Veronese varieties with three or more factors.

Cumulant varieties

Journal of Symbolic Computation, 2006
AbstractFor a discrete distribution in Rd on a finite support D probabilities and moments are algebraically related. If there are n=|D| support points then there are n probabilities p(x),x∈D and n basic moments. By suitable interpolation of the probabilities using a Gröbner basis method, high order moments can be express linearly in terms of n basic ...
