This paper extends recent investigations by Arnold Knopfmacher and John Knopfmacher [10] of asymptotic enumeration questions concerning finite graphs, trees and polyhedra. The present emphasis is on the counting of non-isomorphic maps of not necessarily connected finite graphs on arbitrary surfaces.

β¦ Synopsis
With emphasis on some natural asymptotic enumeration questions, a study is made of various arithmetical semigroups associated with isomorphism classes of finite graphs, trees and polyhedra. A suitable ``abstract prime number theorem'' is derived, particularly as an aid to solving the counting questions stated.

Let S be a locally compact semigroup, let Ο be a weight function on S, and let Ma(S, Ο) be the weighted semigroup algebra of S. Let L β 0 (S; Ma(S, Ο)) be the C \* -algebra of all Ma(S, Ο)-measurable functions g on S such that g/Ο vanishes at infinity. We introduce and study an Arens multiplication
## Abstract The main influences of plants on the mass stability of riverbanks are those that affect the strength of bank sediments. Plants enhance bank strength by reducing poreβwater pressures and by directly reinforcing bank material with their roots. In this paper we do not consider bank hydrolo
