$s$-Hankel hypermatrices and $2\times 2$ determinantal ideals
- Mathematics
- 2016
We introduce the concept of s-Hankel hypermatrix, which generalizes both Hankel matrices and generic hypermatrices. We study two determinantal ideals associated to an s-Hankel hypermatrix: the ideal…

We study notions of robustness of Markov kernels and probability distribution of a system that is described by $n$ input random variables and one output random variable. Markov kernels can be…
2 × 2 Permanental Ideals of Hypermatrices
- Mathematics
- 2011
We analyze the structure of ideals generated by some classes of 2 × 2 permanents of hypermatrices, generalizing [9] on 2 × 2 permanental ideals of generic matrices. We compare the obtained structure…
Matroid stratifications of hypergraph varieties, their realization spaces, and discrete conditional independence models
- Mathematics

We study conditional independence (CI) models in statistical theory, in the case of discrete random variables, from the point of view of algebraic geometry and matroid theory. Any CI model with…
POSITIVE MARGINS AND PRIMARY DECOMPOSITION

We study random walks on contingency tables with fixed marginals, cor- responding to a (log-linear) hierarchical model. If the set of allowed moves is not a Markov basis, then there exist tables with…
