KG(2k+1,k)型Kneser图的b-连续性

On b-continuity Of Kneser Graphs of type KG(2k+1,k)

Saeed Shaebani

摘要:

本文引入了一类特殊的图同态,即半局部满图同态,并给出了半局部满图同态与图的色染色之间的关系,证明了对任意自然数$k$,Kneser图$KG(2k+1,k)$是$b$ -连续的.最后,我们给出了图是$b$ -连续的一些特殊条件。

英文摘要:

In this paper, we will introduce an special kind of graph homomorphisms namely semi-locally-surjective graph homomorphisms and show some relations between semi-locally-surjective graph homomorphisms and colorful colorings of graphs and then we prove that for each natural number $k$, the Kneser graph $KG(2k+1,k)$ is $b$-continuous. Finally, we introduce some special conditions for graphs to be $b$-continuous.
