... we review some standard (and some slightly less standard) Strichartz estimates in three dimensions, and their application to the well- posedness and regularity theory for (1.1). We use L q t L r x to ... expressions of the form O(uv). Proof.Wefixδ, and allow our implicit constants to depend on δ. We begin by addressing the homogeneous case, with u(t):=e itΔ ζ and v(t):=e itΔ ψ and...

... The mapping η is continuous and one-to-one by the strict convexity and smoothness of ∂Ω t . The purpose of introducing the mapping η is to give a more accurate estimate for |T (u k − ϕ)|(p) for ... sufficiently small. In particular (3.30) holds for u t = u t k and u = u t k+1 . From (3.28) and (3.29) we also have an improvement of (2.20) and (2.21), namely for any small δ&...
