A characterization of uniquely representable two-directional orthogonal ray graphs
Asahi Takaoka
In this paper, we provide a characterization of uniquely representable two-directional orthogonal ray graphs, which are defined as the intersection graphs of rightward and downward…
Forbidden patterns of graphs 12-representable by pattern-avoiding words
Asahi Takaoka
A graph is -representable if there is a word over such that two vertices and with are adjacent if and o…
Computing shortest 12-representants of labeled graphs
Asahi Takaoka
The notion of -representable graphs was introduced as a variant of a well-known class of word-representable graphs. Recently, these graphs were shown to be equivalent to the co…
A vertex ordering characterization of simple-triangle graphs
Asahi Takaoka
Consider two horizontal lines in the plane. A pair of a point on the top line and an interval on the bottom line defines a triangle between two lines. The intersection graph of suc…
