 \begin{theorem}[Mathieu]
-  There exists a unique semisimple coherent extension \(\operatorname{Ext}(V)\)
-  of \(V\). More precisely, if \(\mathcal{M}\) is any coherent extension of
-  \(V\), then \(\mathcal{M}^{\operatorname{ss}} \cong \operatorname{Ext}(V)\).
-  Furthermore, \(V\) is itself contained in \(\operatorname{Ext}(V)\) and
-  \(\operatorname{Ext}(V)\) is irreducible as a coherent family.
