Uniqueness of the 2-universality Criterion

Number Theory 2011-01-04 v2

Abstract

Kim, Kim, and Oh gave a minimal criterion for the 2-universality of positive-definite integer-matrix quadratic forms. We show that this 2-universality criterion is unique in the sense of the uniqueness of the Conway-Schneeberger Fifteen Theorem.
