WebSome mammal species inhabiting high-latitude biomes have evolved a seasonal moulting pattern that improves camouflage via white coats in winter and brown coats in summer. In many high-latitude and high-altitude areas, the duration and depth of snow cover has been substantially reduced in the last five decades. This reduction in depth and duration of … Webthe definition) and the topology of cyclic branched coverings of knots. Given a knot K in the 3-sphere S3, we say that a closed connected 3-manifold M is an n-fold cyclic branched covering of K if M is the n-fold cyclic covering of S3 branched over K (see, for exam-ple, [26]). This implies that M is the n-fold cyclic covering of the orbifold O ...

WebA cyclic covering is a covering space for which the set of covering transformations forms a cyclic group. I'll talk about how to construct such covers in AG and as an application, …
WebApr 12, 2024 · To experimentally investigate the effects of the two-way cyclic stress with low-stress amplitude on the cyclic behavior of soft marine clay, a series of triaxial tests is performed on intact marine clay from Zhoushan covering various values of the cyclic stress ratio (CSR) and confining pressure (p′ 0). WebAs the first application, we classify all fibers of 3-cyclic covering fibrations of genus 4 of a ruled surface and show that the signature of a complex surface with this fibration is non-positive by computing the local signature for any fiber.
WebA covering of is a continuous map such that there exists a discrete space and for every an open neighborhood , such that and is a homeomorphism for every . Often, the notion of a covering is used for the covering space as well as for the map . The open sets are called sheets, which are uniquely determined up to a homeomorphism if is connected.
