<∞. For p=1, there is the weak-type (1,1)estimate: (10) μ x: m(P)f(x) >α α−1 f L1, ∀α>0. The outline of this paper is the following: Section 2 will give the proof of the L∞ estimates for the spectral clusters χ λ of the Neumann Laplacian and some WebThe proofs for cases B [resp. C] follow the same pattern. Again, we rewrite the wave equa- tion into its corresponding symmetric hyperbolic first-order system and obtain matrices Ai and B in Mn+2 (GL∞ (UT )). By condition (i) we have that A′i and the symmetric part of B are L1,∞ -log-type [resp. L∞ -log-type].
