Abstract: This paper deals with the uniqueness of solution to a class of semi-linear heatconductmn equation in higher dimension on the basis of references [1] a
An induced matching M in a graph G is a matching such that V(M) induces a1-regular subgraph of G. The induced matching number of a graph G, denoted by IM(G), is
Let G be a3-connected graph with n vertices.The paper proves that if for each pair of verti-ces u and v of G,d(u,v)=2,has|N(u)∩N(v)|≤α(αis the minimum indepe
