Hamilton‐connected {claw, bull}‐free graphs
Original language description
The generalized bull is the graph B(i,j) obtained by attaching endvertices of two disjoint paths of lengths i, j to two vertices of a triangle. We prove that every 3‐connected {K(1,3), X}‐free graph, where X ∈ {B(1,6), B(2,5),B(3,4)}, is Hamilton‐connected. The results are sharp andcomplete the characterization of forbidden induced bulls implying Hamilton‐connectedness of a 3‐connected {claw, bull}‐free graph.
