Diagrams of Knotted Surfaces,scriptions of manifolds, that are convenient for the study of their homology groups, for example. Handle slides and cancelations relate different handle decompositions of the same manifold. Triangulations and their subdivisions are also used for manifolds and complexes.

Quandle Cocycle Invariants,nd announced in ) using cocycles of quandle homology theory. The quandle cocycle knot invariants are natural generalizations of the Dijkgraaf-Witten invariant for 3-manifolds and other state-sum invariants. They have found important topological applications. In this chapter, we review these

r cellular system layout and planning and to evaluate tradeoffs in system design issues. In this paper, we begin with a study of handoff rates in evolving cellular systems. Using simple geometry, we show that in macrocells with homogeneous traffic the handoff rate per call increases only as the squa
