A $40$ -dimensional extremal Type II lattice with no $4$ -frames

Norifumi Ojiro

We construct a $40$ -dimensional extremal Type II lattice not having any subsets consisting of $40$ orthogonal minimal vectors, and determine the automorphism group. This lattice gi…

The trace of modular forms and its application to number theory

Norifumi Ojiro

We provide a generalization of an algebraic linear combination for the trace of certain elliptic modular forms, and through specializing the expression at a suitable pair consistin…
