Numerical Results on Low Mass Star and Brown Dwarf Multiplicity

Eduardo Delgado-Donate, Cathie Clarke

We have undertaken a series of hydrodynamic + N-body simulations in order to explore the properties of young stars. Our results suggest that the IMF may be sensitive to environment…

Cycle Classes of the E-O Stratification on the Moduli of Abelian Varieties

Torsten Ekedahl, Gerard van der Geer

We introduce a stratification on the space of symplectic flags on the de Rham bundle of the universal principally polarized abelian variety in positive characteristic and study its…

Mutually Unbiased Bases and The Complementarity Polytope

Ingemar Bengtsson, Asa Ericsson

A complete set of N+1 mutually unbiased bases (MUBs) forms a convex polytope in the N^2-1 dimensional space of NxN Hermitian matrices of unit trace. As a geometrical object such a…

Mystery of point charges

Andrei Gabrielov, Dmitry Novikov, Boris Shapiro

We discuss the problem of finding an upper bound for the number of equilibrium points of a potential of several fixed point charges in R^n. This question goes back to J.C.Maxwell a…

On rational approximation of algebraic functions

Julius Borcea, Rikard Bögvad, Boris Shapiro

We construct a new scheme of approximation of any multivalued algebraic function by a sequence of rational functions. The latter sequence is…
