The notion of 1-plane and 1-planar graphs was first introduced by Ringel in connection with the problem of simultaneous coloring of the vertices and faces of plane graphs. In particular, in contrast to planarity testing, testing 1-planarity of a given graph is an NP-complete problem. Even ...
1-Planar GraphCombinatorial ProblemThe bondage number of a nonempty graph G is the cardinality of a smallest set of edges whose removal from G results in a graph a domination number greater than the domination number of G. In this paper, we prove that for a 1-planar graph G....
A planar graphis a graph that can be drawn on a plane in such a way that no edges cross each other, and this drawing is a plane graph. For example, in Figure 1, the first graph is a complete graph of order 4, denoted by K4, which is planar graph. The second graph is an embedd...
A graph is outer 1-planar (o1p) if it can be drawn in the plane such that all vertices are in the outer face and each edge is crossed at most once. o1p graphs generalize outerplanar graphs, which can be recognized in linear time, and specialize 1-planar graphs, whose recognition is...

Planar graphs without 5- and 7-cycles and without adjacent triangles are 3-colorable It is known that planar graphs without cycles of length from 4 to 7 are 3-colorable [O.V. Borodin, A.N. Glebov, A. Raspaud, M.R. Salavatipour, Planar graph... OV Borodin,AN Glebov,M Montassier...
Triplanar is a method of generating UVs and sampling a texture by projecting in world space. The input Texture is sampled 3 times, once in each of the world x, y and z axises, and the resulting information is planar projected onto the model, blended by the normal, or surface angle. ...
