Abstract
Actions of SL 2(ℝ) on the half-plane. In the theory of modular or more generally automorphic functions, one uses the group46 G = SL 2(ℝ) of matrices \(g = \left(\begin{array}{*{10}c} a & b \\ c & d \end{array}\right)\) and so \(g^{-1} = \left(\begin{array}{*{10}c} d & -b \\ -c & a \end{array}\right)\).
