Abstract: If X is an orientable, strongly minimal PD4-complex and π1(X) has one end, then it has no nontrivial locally finite normal subgroup. Hence, if π is a 2-knot group, then (a) if π is virtually… read more here.

Abstract: In this paper we introduce the special rank for virtual knots and some properties of this number are studied. Although we do not know if it can be considered as a nontrivial extension of the… read more here.
