WebSep 25, 2024 · Sometimes we must resort to trickier methods in order to decide whether or not two groups are isomorphic. Example 3.3.5. The groups Z and Q are not isomorphic. We use contradiction to prove this. Suppose that Z and Q are isomorphic via isomorphism ϕ: Q → Z. Let a ∈ Q. Then a 2 ∈ Q with a 2 + a 2 = a. Then. WebSep 16, 2024 · Example 5.6.2: Matrix Isomorphism. Let T: Rn → Rn be defined by T(→x) = A(→x) where A is an invertible n × n matrix. Then T is an isomorphism. Solution. The reason for this is that, since A is invertible, the only vector it sends to →0 is the zero vector. Hence if A(→x) = A(→y), then A(→x − →y) = →0 and so →x = →y.
