We give several bounds for the number of isolated factorizations of simplicial affine semigroups and numerical semigroups. We also generalize [Formula: see text]-rectangular numerical semigroups to the context of simplicial affine semigroups and study their isolated factorizations. As a consequence of our results, we characterize those complete intersection simplicial affine semigroups with only one Betti minimal element in several ways. Moreover, we define Betti sorted and Betti divisible simplicial affine semigroups and characterize them in terms of gluings and their minimal presentations. Finally, we determine all the Betti divisible numerical semigroups, which turn out to be those numerical semigroups that are free for any arrangement of their minimal generators. <\/jats:p>","DOI":"10.1142\/s0219498820500826","type":"journal-article","created":{"date-parts":[[2019,3,20]],"date-time":"2019-03-20T09:19:11Z","timestamp":1553073551000},"page":"2050082","source":"Crossref","is-referenced-by-count":6,"title":["Isolated factorizations and their applications in simplicial affine semigroups"],"prefix":"10.1142","volume":"19","author":[{"given":"Pedro A.","family":"Garc\u00eda-S\u00e1nchez","sequence":"first","affiliation":[{"name":"Departamento de \u00c1lgebra, Universidad de Granada, Avenida de Fuente Nueva S\/N, E-18071 Granada, Espa\u00f1a"}]},{"given":"Andr\u00e9s","family":"Herrera-Poyatos","sequence":"additional","affiliation":[{"name":"Departamento de \u00c1lgebra, Universidad de Granada, Avenida de Fuente Nueva S\/N, E-18071 Granada, Espa\u00f1a"}]}],"member":"219","published-online":{"date-parts":[[2019,5,3]]},"reference":[{"key":"S0219498820500826BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsc.2007.07.012"},{"key":"S0219498820500826BIB002","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-41330-3"},{"key":"S0219498820500826BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/0021-8693(77)90268-X"},{"key":"S0219498820500826BIB004","unstructured":"W.
