设V是有限交换环R上的辛空间,G SpR(V)是R上的辛图。本文证明了它是弧传递的,并确定了它的色数。此外,如果R是有限局部环,我们得到了它的自同构群,以及每个子成分的色数和自同构群。
Let V be a symplectic space over a finite commutative ring R and let G Sp R (V) be the symplectic graph over R. In this work, we show that it is arc transitive and determine the chromatic number. Moreover, if R is a finite local ring, we obtain its automorphism group, and the chromatic number and the automorphism group of each subconstituent.
