Classes of integral 3-tensors on 2-space
Published online by Cambridge University Press: 26 February 2010
Abstract
The space of integral 3-tensors is under the standard action of . A notion of primitivity is defined in this space and the number of primitive classes of a given discriminant is evaluated in terms of the class number of primitive binary quadratic forms of the same discriminant. Classes containing symmetric 3-tensors are also considered and their number is related to the 3-rank of the class group.
