Homothetic covering of convex hulls of compact convex sets
Senlin Wu, Keke Zhang, Chan He
Let be a compact convex set and be a positive integer. The covering functional of with respect to is the smallest such that can be covered by tr…
Generalized Catalan numbers
Keke Zhang
A finitization of the Catalan numbers can be defined as Euler characteristics of an algebraic structure. We conjecture the existence of a -deformed version of such str…
Parallel finite volume simulation of the spherical shell dynamo with pseudo-vacuum magnetic boundary conditions
Liang Yin, Chao Yang, Shi-Zhuang Ma +2
In this paper, we study the parallel simulation of the magnetohydrodynamic (MHD) dynamo in a rapidly rotating spherical shell with pseudo-vacuum magnetic boundary conditions. A sec…
Shapes and gravitational fields of rotating two-layer Maclaurin ellipsoids: Application to planets and satellites
Gerald Schubert, John D. Anderson, Keke Zhang +2
The exact solution for the shape and gravitational field of a rotating two-layer Maclaurin ellipsoid of revolution is compared with predictions of the theory of figures up to third…
Spherical, Oscillatory -Dynamo Induced by Magnetic Coupling Between a Fluid Shell and an Inner Electrically Conducting Core: Relevance to the Solar Dynamo
G. Schubert, K. Zhang
A two-layer spherical -dynamo model consisting of an inner electrically conducting core (magnetic diffusivity and radius ) with surrounded by an electrically…
