On Povzner--Wienholtz-type Self-Adjointness Results for Matrix-Valued Sturm--Liouville Operators

We derive Povzner–Wienholtz-type self-adjointness results for $m\times m$ matrix-valued Sturm–Liouville operators $T=R^{-1}[-\text{f}ddxP\text{f}ddx+Q]$ in $L^2((a,b);Rdx{)}^m$, $m\in \text{bbN}$, for $(a,b)$ a half-line or $\text{bbR}$.
