On minimal triangle-free graphs with prescribed k-defective chromatic number

A graph G is (m, k)-colourable if its vertices can be coloured with m colours such that the maximum degree of any subgraph induced on vertices receiving the same colour is at most k. The k-defective chromatic number χk(G) is the least positive integer m for which G is (m, k)-colourable. Let f(m, k)...
