On the basis number of the corona of graphs
The basis number b(G) of a graph G is defined to be the least integer k such that G has a k-fold basis for its cycle space. In this note, we determine the basis number of the corona of graphs, in fact we prove that b(v∘T)=2 for any tree and any vertex v not in T, b(v∘H)≤b(H)+2, where H is any graph...
