圖的符號邊控制數(shù)有著許多重要的應用背景.已知它的計算是NP-完全問題,因而確定其精確值有重要意義.本文確定了圖、Hn和的符號邊控制數(shù).

The signed edge dom ination number of a graph has its im port and applying background.It is known that com pu ting it is NP-com p lete,so it is usefu l to determ inate the exact value of it.In this paper,we determ ine the signed edge dom ination numbers of graph F?n+1、Hnand P?n.
