Hyperuniformity near jamming transition over a wide range of bidispersity
Duc T. Dam, Takeshi Kawasaki, Atsushi Ikeda +1
We numerically investigate hyperuniformity in two-dimensional frictionless jammed packings of bidisperse systems. Hyperuniformity is characterized by the suppression of density flu…

Prym loci of branched double coverings and generalized Andreotti-Mayer loci
Atsushi Ikeda
The Andreotti-Mayer locus is a subset of the moduli space of principally polarized abelian varieties, defined by a condition on the dimension of the singular locus of the theta div…
