Even universal binary Hermitian lattices over imaginary quadratic fields

Number Theory 2009-02-19 v2

Abstract

A positive definite even Hermitian lattice is called \emph{even universal} if it represents all even positive integers. We introduce a method to get all even universal binary Hermitian lattices over imaginary quadratic fields \Qm\Q{-m} for all positive square-free integers mm and we list optimal criterions on even universality of Hermitian lattices over \Qm\Q{-m} which admits even universal binary Hermitian lattices.
