Zhao Hai · Journal of Qinghai Normal University · 2000
Let A denote the graph obtained from identifying two vertices of Z r with one of the vertex of degree 1 in path respectively,B denote the graph obtained from identifying a vertex of Z r with one of the vertex of degree 1 in T-shape tree.In this paper,we show that A and B are circuit unique.
