3. Prove that the set of matrices of the form 1 x y 01 2 0 0 1, is a group under ordinary matrix multiplication. This group is known as the Heisenberg group, and is an important tool in the theory of quantum me- chanics. Is this group abelian? Why or why not? 4. Prove that in GL2 (R), det (AB) = det(A) det (B). Then, prove that this fact implies the closure of the binary operation in the group GL2(R).
