Abstract
Let be a manifold with nonpositive sectional curvature and bounded geometry, and let be a uniformly embedded submanifold of We estimate the norm of a -scale spectral projection operator. It is a generalization of result of X. Chen to noncompact cases. We also prove sharp spectral projection estimates of spectral windows of any small size restricted to nontrapped geodesics on even asymptotically hyperbolic surfaces with bounded geometry and curvature pinched below 0.
