The Dynamics of Collapsing Monopoles and Regular Black Holes
A black hole thin shell magnetic monopoles dynamic static configuration high energy laser
2014/12/22
We study the formation and stability of regular black holes by employing a thin shell approximation to the dynamics of collapsing magnetic monopoles. The core deSitter region of the monopole is matche...
Collapsing and essential coverings
the Gromov-Hausdorff convergence Alexandrov spaces Betti numbers
2012/5/25
In the present paper, we consider the family of all compact Alexandrov spaces with curvature bound below having a definite upper diameter bound of a fixed dimension. We introduce the notion of essenti...
Collapsing 4-manifolds under a lower curvature bound
collapsing Gromov-Hausdorff convergence Alexandrov spaces topology of 4-manifolds
2012/5/24
In this paper we describe the topology of 4-dimensional closed orientable Riemannian manifolds with a uniform lower bound of sectional curvature and with a uniform upper bound of diameter which collap...

Pre-big bang collapsing universe modern Kaluza-Klein theory gravity
2011/10/18
We study the collapse of the universe described by a scalar field spherically symmetric collapse of a system described by a massless scalar field from a 5D Riemann-flat canonical metric, on which we m...
We investigate the effect of induced massive radiation given off during the time of collapse of a massive spherically symmetric domain wall in the context of the functional Schr\"odinger formalism. H...

Peering Under the Ice of a Collapsing Polar Coast--Low-Level Aerial Surveys Aim to Understand Rapid Antarctic Melting（图）
the Ice of a Collapsing Polar Coast Low-Level Aerial Surveys Rapid Antarctic Melting
2009/12/10
Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace ...
Simultaneous monitoring of a collapsing landslide with video cameras
Simultaneous monitoring collapsing landslide video cameras
2010/1/27
Effective countermeasures and risk management to reduce landslide hazards require a full understanding of the processes of collapsing landslides. While the processes are generally estimated from the f...
Collapsing D-Branes in Calabi-Yau Moduli Space: I
Collapsing D-Branes Calabi-Yau Moduli Space
2010/11/2
We study the quantum volume of D-branes wrapped around various cycles in Calabi-Yau manifolds, as the manifold's moduli are varied. In particular, we focus on the behaviour of these D-branes near phas...
