On dually-CPT and strong-CPT posets
Liliana Alcón, Martin Charles Golumbic, Noemí Gudiño +2
A poset is a containment of paths in a tree (CPT) if it admits a representation by containment where each element of the poset is represented by a path in a tree and two elements a…
Convex geometries over induced paths with bounded length
Marisa Gutierrez, Fábio Protti, Silvia B. Tondato
Graph convexity spaces have been studied in many contexts. In particular, some studies are devoted to determine if a graph equipped with a convexity space is a {\em convex geometry…
Weakly toll convexity and proper interval graphs
Mitre C. Dourado, Marisa Gutierrez, Fábio Protti +1
A walk is a \textit{weakly toll walk} if implies and implies . A set of vertices of i…
Characterizations of graph classes via convex geometries: a survey
Mitre C. Dourado, Marisa Gutierrez, Fábio Protti +2
Graph convexity has been used as an important tool to better understand the structure of classes of graphs. Many studies are devoted to determine if a graph equipped with a convexi…
