this paper provides an analysis of persian verbs within the framework of optimality theory. to be more specific, it mainly cocentrates on past and present stems of persian verbs. since analyzing this subject within the derivational framework would result phonological rules which are not natural, it is analysed by optimality theory which is one of the constraint-based approach. based on this, we...

In 1998 Burago and Kleiner (independently) McMullen gave examples of separated nets in Euclidean space which are bilipschitz non-equivalent to the integer lattice. We study weaker notions than equivalence demonstrate that such also distinguish between nets. Put differently, we find occurrences particularly strong divergence from Our approach generalises takes place largely a continuous setting....
