Summary: We investigate the local spectral behaviour of (constant coefficient) matrix differential operators, and more general matrix $p$-multiplier operators, in $L^p$-spaces $($particularly, over $\mathbb R^N$$)$. Of particular interest is the decomposability and spectral mapping properties of such operators, together with relevant functional calculi, when they are available.

Keywords: $L^p$-spaces, matrix $p$-multipliers, decomposability, functional calculi.
