Let A be an abelian variety of GL 2 -type over the rational number field Q, without complex multiplication. In this paper, we will show that a modularity of A over the complex number field C implies that of A over Q.

✦ Synopsis
The a-invariant is determined and a description of the defining ideal for the set S K of rational points of the Segre variety over a finite field K is given. The dimension as well as the minimum distance of a Reed-Muller-type linear code defined over S K are also determined. An example is given to illustrate the ideas.

In this paper, we consider the problem of the existence of a basis of orthogonal vectors of norm 2k in the Leech lattice. Recently it has been shown that there is such a basis for every k ( 2) which is not of the form 11 r . In this paper, this problem is completely settled by finding such a basis f
