Abstract
We consider terms in which some patterns can be repeated n times. n is an integer variable which is part of the syntax of the terms (and hen ce may occur more than once in them). We show that unification of such terms is decidable and finitary, extending Chen and Hsiang's result o n p-term unification. Finally, extending slightly the syntax yields an undecidable unification problem.
