Question

3. Let G be the subgroup of GL2(R) consisting of matrices of the form $G = \left\{ \begin{bmatrix} x & y \\ 0 & 1 \end{bmatrix} \right\}$, and H the subgroup of G consisting of matrices of the form $H = \left\{ \begin{bmatrix} t & 0 \\ 0 & 1 \end{bmatrix} \mid t \in \mathbb{R}_{>0} \right\}$. An element in G can be represented by a point (x, y) in R² (minus the y-axis). Draw the partition of the plane into left and right cosets of H.

Step 1

G consists of matrices of the form: G = { [[a, b], [c, d]] | a, b, c, d ∈ R, ad - bc ≠ 0 } H consists of matrices of the form: H = { [[a, 0], [c, d]] | a, c, d ∈ R, ad ≠ 0 } Show more…
