Consider the group $G = \left\{\begin{pmatrix} a & b\\ 0 & 1\end{pmatrix}: a \in \mathbb{C}^{\times}, b \in \mathbb{C}\right\} \subset GL(2, \mathbb{C})$. How does one find the universal cover of this group? In general, if I had a larger explicit matrix, what would I do?

    @109230: okay. Do you know how to find the universal cover of $\mathbb{C}^{\times}$?2012-04-03
