- h-COBORDISMS AND MAPPING CYLINDER OBSTRUCTIONS. Vajiac, Bogdan // Journal of the Australian Mathematical Society;Apr2009, Vol. 86 Issue 2, p249
In this paper we prove a realizability theorem for Quinn's mapping cylinder obstructions for stratified spaces. We prove a continuously controlled version of the s-cobordism theorem which we further use to prove the relation between the torsion of an h-cobordism and the mapping cylinder...

- The performance of the OSRC method for concentric penetrable circular cylinder. Yılmaz, Bülent // Journal of Mathematical Physics;Apr2006, Vol. 47 Issue 4, p043515
In this paper we consider the scattering of a wave by concentric penetrable circular cylinder to examine the performance of higher order SRCs up to the L4 operator in two dimensions. We assume that in the rectangular Cartesian axes, (x,y,z), the z axis coincides with the axis of a cylinder and...

- Mean curvature flow of a hyperbolic surface. Ovchinnikov, Yu.; Sigal, I. // Journal of Experimental & Theoretical Physics;Dec2011, Vol. 113 Issue 6, p1063
A four-parameter family of self-similar solutions is obtained to the mean curvature flow equation for a surface. This family is shown to be stable with respect to a small deformation of a hyperbolic surface. At time instant t*, a singular point is formed within a finite time interval, that is...
