We study locally flat, compact, oriented surfaces in $4$-manifolds whose exteriors have infinite cyclic fundamental group. give algebraic topological criteria for two such surfaces, with the same genus $g$, to be related by an ambient homeomorphism, and further that imply they are ambiently isotopic. Along way, we prove certain pairs of group, homeomorphic boundaries, equivalent equivariant int...
This is an expository paper on work of Endo and Miyata which leads to a computation of the flabby class group of a finite cyclic group.
Suppose G is a group of order p^2q^2 where p>q are prime numbers and suppose P and Q are Sylow p-subgroups and Sylow q-subgroups of G, respectively. In this paper, we show that up to isomorphism, there are four groups of order p^2q^2 when Q and P are cyclic, three groups when Q is a cyclic and P is an elementary ablian group, p^2+3p/2+7 groups when Q is an elementary ablian group an...
Abstract Background and Aim : Microgap in the implant-abutment interface is one of the main challenges in the treatment of two-piece implants. This study aimed to investigate the effect of two types of abutments (zirconia and titanium) on microgap at implant-abutment interface area under oblique cyclic loading in vitro. Methods and Materials In this in vitro study, 12 implant-abutment assemb...
