John O’M Bockris,Amulya K. N. Reddyen a knot diagram of treewidth two, does it represent the trivial knot? We also show that for a link diagram of treewidth two we can test in linear time if it represents the unlink. From the algorithm, it follows that a diagram of the trivial knot of treewidth 2 can always be reduced to the trivial

Such graph classes are known to have useful algorithmic applications related to variants of the clique and .-coloring problems. We consider six well-known graph c
