In this paper, we first characterize all graphs G satisfying e ( G ) + c ( G ) ≥ n ( n + 1 ) ∕ 2 − 1 but containing no rainbow triangles . 이 논문에서는 먼저 e ( G ) + c ( G ) ≥ n ( n + 1 ) ∕ 2 − 1 을 만족하지만 무지개 ... WebJul 1, 2004 · Journal of Graph Theory. We show some consequences of results of Gallai concerning edge colorings of complete graphs that contain no tricolored triangles. We prove two conjectures of Bialostocki and Voxman about the existence of special monochromatic spanning trees in such colorings. We also determine the size of largest …

Authors: Peter Frankl, Ervin Győri, Zhen He, ... we provide a counterexample to a conjecture of Frankl on the maximum product of the sizes of the edge sets of three graphs avoiding a rainbow triangle. Moreover we propose an alternative conjecture and prove it in the case when … WebJul 7, 2024 · The following four results discuss the lower bound of , as is an edge-colored complete graph containing no rainbow triangles, properly colored 4-cycles, or monochromatic 4-cycles.

Let be an … WebDec 1, 2024 · Let G be an edge-colored graph of order n. If d c ( v) ≥ n 2 for every vertex v ∈ V ( G) and G contains no rainbow triangles, then n is even and G is the complete bipartite graph K n 2, n 2, unless G = K 4 − e or K 4 when n = 4. The rest of the paper is organized as follows. In Section 3, we first prove Theorem 3. order in which the states became states
