The Isomorphism Problem for k-Trees is Complete for Logspace

Revisions: 1

We show that k-tree isomorphism can be decided in logarithmic
space by giving a logspace canonical labeling algorithm. This improves
over the previous StUL upper bound and matches the lower bound. As a
consequence, the isomorphism, the automorphism, as well as the
canonization problem for k-trees ... more >>>
