Abstract in LaTeX format:
We present a randomized and a deterministic
data structure for maintaining a dynamic family of
sequences under equality--tests of pairs of sequences and creations
of new sequences by joining or splitting existing sequences.
Both data structures support equality--tests in $O(1)$ time. The
randomized version supports new sequence creations in $O(\log^2 n)$
expected time
where $n$ is the length of the sequence created. The
deterministic solution supports sequence creations in
$O(\log n(\log m \log^* m + \log n))$ time for the $m$--th operation.
