Abstract

For a family H\mathcal{H} of graphs, a graph GG is said to be {\it H\mathcal{H}-free} if GG contains no member of H\mathcal{H} as an induced subgraph. We let G~3(H)\tilde{\mathcal{G}}_{3}(\mathcal{H}) denote the family of connected H\mathcal{H}-free graphs having minimum degree at least 33. In this paper, we characterize the non-caterpillar trees TT having diameter at least 77 such that G~3({C3,C4,T})\tilde{\mathcal{G}}_{3}(\{C_{3},C_{4},T\}) is a finite family, where CnC_{n} is a cycle of order nn.
