The rank of new regular quadratic forms

Mingyu Kim, Byeong-Kweon Oh

A (positive definite and integral) quadratic form $f$ is called regular if it represents all integers that are locally represented. It is known that there are only finitely many re…

Isolations of cubic lattices from their proper sublattices

Byeong-Kweon Oh

A (positive definite and integral) quadratic form is called {\it an isolation} of a quadratic form $f$ if it represents all subforms of $f$ except for $f$ itself. The minimum rank…

Tight universal quadratic forms

Mingyu Kim, Byeong-Kweon Oh

For a positive integer $n$ , let $T (n)$ be the set of all integers greater than or equal to $n$ . An integral quadratic form $f$ is called tight $T (n)$ -universal if…
