--- res: bibo_abstract: - We consider the three-state toric homogeneous Markov chain model (THMC) without loops and initial parameters. At time T, the size of the design matrix is 6 × 3 · 2T-1 and the convex hull of its columns is the model polytope. We study the behavior of this polytope for T ≥ 3 and we show that it is defined by 24 facets for all T ≥ 5. Moreover, we give a complete description of these facets. From this, we deduce that the toric ideal associated with the design matrix is generated by binomials of degree at most 6. Our proof is based on a result due to Sturmfels, who gave a bound on the degree of the generators of a toric ideal, provided the normality of the corresponding toric variety. In our setting, we established the normality of the toric variety associated to the THMC model by studying the geometric properties of the model polytope.@eng bibo_authorlist: - foaf_Person: foaf_givenName: David foaf_name: Haws, David foaf_surname: Haws - foaf_Person: foaf_givenName: Abraham foaf_name: Martin Del Campo Sanchez, Abraham foaf_surname: Martin Del Campo Sanchez foaf_workInfoHomepage: http://www.librecat.org/personId=4CF47F6A-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Akimichi foaf_name: Takemura, Akimichi foaf_surname: Takemura - foaf_Person: foaf_givenName: Ruriko foaf_name: Yoshida, Ruriko foaf_surname: Yoshida bibo_doi: 10.1007/s13366-013-0178-y bibo_issue: '1' bibo_volume: 55 dct_date: 2014^xs_gYear dct_language: eng dct_publisher: Springer@ dct_title: Markov degree of the three-state toric homogeneous Markov chain model@ ...
