Abstract

In this work we study weighted Sobolev spaces in Rⁿ generated by the Lie algebra of vector fields (1 + x ²)^1/2 ∂_xj, j = 1, ..., n. Interpolation properties and Sobolev embeddings are obtained on the basis of a suitable localization in Rⁿ. As an application we derive weighted L^q estimates for the solution of the homogeneous wave equation. For the inhomogeneous wave equation we generalize the weighted Strichartz estimate established by V. Georgiev (1997, Amer. J. Math. 119, 1291-1319) and establish global existence results for the supercritical semilinear wave equation with non-compact small initial data in these weighted Sobolev spaces.
