Current singularities at finitely compressible three-dimensional magnetic null points

The formation of current singularities at line-tied twoand three-dimensional 2D and 3D, respectively magnetic null points in a nonresistive magnetohydrodynamic environment is explored. It is shown that, despite the different separatrix structures of 2D and 3D null points, current singularities may be initiated in a formally equivalent manner. This is true no matter whether the collapse is trigg...

Formation of Singularities in Three-Dimensional Compressible Fluids

Presented are several results on the formation of singularities in solutions to the three-dimensional Euler equations for a polytropic, ideal fluid under various assumptions on the initial data. In particular, it is shown that a localized fluid which is initially compressed and outgoing, on average, will develop singularities regardless of the size of the initial disturbance. This article prese...

Current sheets at three-dimensional magnetic nulls: Effect of compressibility

The nature of current sheet formation in the vicinity of three-dimensional magnetic null points is investigated. The particular focus is upon the effect of the compressibility of the plasma on the qualitative and quantitative properties of the current sheet. It is found that as the incompressible limit is approached, the collapse of the null point is suppressed, and instead an approximately pla...

Singularities at rims in three - dimensional fluid flow

Asymptotic solutions are presented for Stokes flow near circular rims in three dimensional geometries. Using nonstandard toroidal coordinates, asymptotic analytical expressions are derived for different corner angles. In comparison to the two-dimensional case, an extra critical corner angle value is derived, below which the swirling behavior of a particle is absent. Illustrations of the motion ...

Three Dimensional SCFT from M2 Branes at Conifold Singularities

Recently it was conjectured that parallel branes at conical singularities are related to string/M theory on AdS×X where X is an Einstein manifold. In this paper we consider coincident M2 branes near a conifold singularity when M theory is compactified on AdS4×Q for Q = (SU(2)×SU(2)× SU(2))/(U(1)× U(1)) as a seven dimensional Sasaki-Einstein manifold. We argue that M theory on AdS4 × Q can be de...
