WebMar 7, 2016 · We can show that an elementary tensor x ⊗ y is nonzero by giving an R -bilinear map B: E × F → M such that B ( x, y) ≠ 0. As an example, consider E = F = Z as Z -modules and the Z -bilinear map B: Z × Z → Z given by multiplication: B ( x, y) = x y. Then if x, y ≠ 0, B ( x, y) ≠ 0, so that x ⊗ y ≠ 0 in Z ⊗ Z Z when x, y ≠ 0. Share Cite Follow WebOct 3, 2024 · Select a Web Site.
