Query: $L^{p}$ estimates for joint quasimodes of semiclassical
  pseudodifferential operators   We develop a set of $L^{p}$ estimates for functions $u$ that are a joint
quasimode (approximate eigenfunction) of $r$ pseudodifferential operators
$p_{1}(x,hD),\dots,p_{r}(x,hD)$. This work extends Sarnak and Marshall's work
on symmetric space to cover a more general class of manifolds/operators.
