Uniqueness of the 2-universality Criterion


Abstract


En
Kim, Kim, and Oh gave a minimal criterion for the 2-universality of positivedefinite 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.
