Webanti-Ramsey numbers are closely related to planar Tura´n numbers, where the planar Tura´n number of H is the maximum number of edges of a planar graph on nvertices without containing H as a subgraph. The study of ar P (n,H) (under the name of rainbow numbers) was initiated by Hornˇa´k, Jendrol′, Schiermeyer and Sota´k [J Graph Theory 78 ...
WebJan 25, 2024 · We investigate a variation of this problem with the additional restriction that the graph is planar, and we denote the corresponding extremal number by ex ∗P ( n, F ). In particular, we determine ex ∗P ( n, P 5 ), where P 5 denotes the 5-vertex path. ... On the rainbow planar Tur\'an number of paths @inproceedings{GyHori2024OnTR, title={On ...
