Thinking, as naively as possible, of an element of $LGL_n$ as a sequence of matrices $(g_i)_{i \in \mathbbZ}$ where $g_i = I$ for almost all negative $i$, and there is some inverse sequence $(h_i)$, then Faltings's result tells us "most" such sequences should be of the form $((g_i)_{i < 0}, (g_i)_{i \ge 0})$, where there are respective inverses for the two parts: $(h'_i)_{i < 0}$ and $(h''_i)_{i \ge 0}$. But if this intuition is reasonable, there is no reason most sequences should be allowed to have a gap, i.e. $g_i=0$ for $i$ from $-n$ to $-1$ | |
