Fibrations of simplicial sets
Tibor Beke
There are infinitely many variants of the notion of Kan fibration that, together with suitable choices of cofibrations and the usual notion of weak equivalence of simplicial sets,…
Satellite Observations of Separator Line Geometry of Three-Dimensional Magnetic Reconnection
C. J. Xiao, X. G. Wang, Z. Y. Pu +14
Detection of a separator line that connects magnetic nulls and the determination of the dynamics and plasma environment of such a structure can improve our understanding of the thr…
Exact Solutions of the Isothermal Lane--Emden Equation with Rotation and Implications for the Formation of Planets and Satellites
Dimitris M. Christodoulou, Demosthenes Kazanas
We have derived exact solutions of the isothermal Lane--Emden equation with and without rotation in a cylindrical geometry. The corresponding hydrostatic equilibria are most releva…
An Efficient Local Approach to Convexity Testing of Piecewise-Linear Hypersurfaces
Konstantin Rybnikov
We show that a closed piecewise-linear hypersurface immersed in () is the boundary of a convex body if and only if every point in the interior of each -face ha…
Bonnesen-type inequalities for surfaces of constant curvature
Daniel A. Klain
A Bonnesen-type inequality is a sharp isoperimetric inequality that includes an error estimate in terms of inscribed and circumscribed regions. A kinematic technique is used to pro…
Perfect Delaunay Polytopes in Low Dimensions
Mathieu Dutour, Robert Erdahl, Konstantin Rybnikov
A lattice Delaunay polytope is known as perfect if the only ellipsoid, that can be circumscribed about it, is its Delaunay sphere. Perfect Delaunay polytopes are in one-to-one corr…
