Inapproximability of maximal strip recovery
Minghui Jiang
In comparative genomic, the first step of sequence analysis is usually to decompose two or more genomes into syntenic blocks that are segments of homologous chromosomes. For the re…
Dispersion in disks
Adrian Dumitrescu, Minghui Jiang
We present three new approximation algorithms with improved constant ratios for selecting points in disks such that the minimum pairwise distance among the points is maximi…
Fractal Weyl law behavior in an open, chaotic Hamiltonian system
Jordan A. Ramilowski, S. D. Prado, F. Borondo +1
We numerically show fractal Weyl law behavior in an open Hamiltonian system that is described by a smooth potential and which supports numerous above-barrier resonances. This behav…
Polynomial 6j-Symbols and States Sums
Nathan Geer, Bertrand Patureau-Mirand
For q a root of unity of order 2r, we give explicit formulas of a family of 3-variable Laurent polynomials J_{i,j,k} with coefficients in Z[q] that encode the 6j-symbols associated…
Rank 2 distributions of Monge equations: symmetries, equivalences, extensions
Ian Anderson, Boris Kruglikov
By developing the Tanaka theory for rank 2 distributions, we completely classify classical Monge equations having maximal finite-dimensional symmetry algebras with fixed (albeit ar…
Secondary Chern-Euler forms and the Law of Vector Fields
Zhaohu Nie
The Law of Vector Fields is a term coined by Gottlieb for a relative Poincaré-Hopf theorem. It was first proved by Morse and expresses the Euler characteristic of a manifold with b…
