Apr 15, 2015 at 11:53 | comment | added | Tomas | Yes, there is a log improvement for $L^{\infty}$ norm of the eigenfunction for manifolds with negative curvature. Actually, it's proved recently that there is also a log improvement for $L^p$ norm with $p>\frac{2(n+1)}{n-1}$. The classical $L^p$ norm s(including $p=\infty$)for general manifolds was first proved by C.D.Sogge, and the result is sharp by testing spherical harmonics. You can find this in his book "Fourier integrals in classical analysis". | |
