Tensor Products of Positive definite Quadratic forms III
Published online by Cambridge University Press: 22 January 2016
Extract
In the previous papers [2], [3] we treated the following two questions. Let L,M,N be positive definite quadratic lattices over Z:
(i) If L, M are indecomposable, then is L⊗M indecomposable?
(ii) Does L ⊗ M ⋍ L ⊗ N imply M ⋍ N?
