Polycyclic-by-finite group algebras are catenary
arXiv:math/9808123
Abstract
We show that group algebras kG of polycyclic-by-finite groups G, where k is a field, are catenary: Given prime ideals P and P' of kG, with P contained in P', all saturated chains of primes between P and P' have the same length.
