There is a close relationship between word unification and second-order unification. This similarity has been exploited for instance for proving decidability of monadic second-orde...
We show that simultaneous rigid E-unification, or SREU for short, is decidable and in fact EXPTIME-complete in the case of one variable. This result implies that the fragment of i...
