On the dimension of the strongly robust complex for configurations in general position
Dimitra Kosta, Apostolos Thoma, Marius Vladoiu
Strongly robust toric ideals are the toric ideals for which the set of indispensable binomials is the Graver basis. The strongly robust simplicial complex of a simple toric i…
The strongly robust simplicial complex of monomial curves
Dimitra Kosta, Apostolos Thoma, Marius Vladoiu
To every simple toric ideal one can associate the strongly robust simplicial complex , which determines the strongly robust property for all ideals that have as th…
On the strongly robustness property of toric ideals
Dimitra Kosta, Apostolos Thoma, Marius Vladoiu
To every toric ideal one can associate an oriented matroid structure, consisting of a graph and another toric ideal, called bouquet ideal. The connected components of this graph ar…
Embeddability of centrosymmetric matrices capturing the double-helix structure in natural and synthetic DNA
Muhammad Ardiyansyah, Dimitra Kosta, Jordi Roca-Lacostena
In this paper, we discuss the embedding problem for centrosymmetric matrices, which are higher order generalizations of the matrices occurring in Strand Symmetric Models. These mod…
The Model-Specific Markov Embedding Problem for Symmetric Group-Based Models
Muhammad Ardiyansyah, Dimitra Kosta, Kaie Kubjas
We study model embeddability, which is a variation of the famous embedding problem in probability theory, when apart from the requirement that the Markov matrix is the matrix expon…
Maximum Likelihood Estimation of Toric Fano Varieties
Carlos Améndola, Dimitra Kosta, Kaie Kubjas
We study the maximum likelihood estimation problem for several classes of toric Fano models. We start by exploring the maximum likelihood degree for all -dimensional Gorenstein…
