We establish conditions for the existence of nontrivial convex covers and nontrivial convex partitions of trees. We prove that a tree G on n ≥ 4 vertices has a nontrivial convex p-cover for every p, 2 ≤ p ≤ 'max cn (G). Also, we prove that it can be decided in polynomial time whether a tree on n ≥ 6 vertices has a nontrivial convex p-partition, for a fixed p, 2 ≤ p ≤ ⌊ n 3 ⌋. |
