On the nash-moser iteration technique
WebThis idea is at the basis of the Nash-Moser theorem, which allows to overcome the problem of the loss of derivatives in nite regularity (see chapter 3). The outline of the lectures is … Webat each step of the Nash-Moser iteration we ensure the invertibility of the linearized operators only on smaller and smaller sets of \non-resonant" parameters. A task of the iteration is to prove that, at the end of the recurrence, we have obtained a positive measure set of parameters where the solution is de ned.

In particular, the nonlinear stability and existence of compressible vortex sheet solutions under small perturbations are established by using a modification of the Nash-Moser iteration technique, where a … WebAn important reference on Nash–Moser-type theorems is Hamilton [4]. Another good reference is Alinhac and G´erard’s book [1]. Plan of the paper and scheme of the main …
WebAs it is well-known, the Nash-Moser approach is natural to use in situations where a loss of regularity prevents the application of other, more standard iteration schemes (con- … WebThe aim of this work is to provide a brief presentation of the Nash-Moser iteration technique for the resolution of nonlinear equations, where the linearized equations admit estimates with a loss of regularity with respect to the given data.
Webiteration technique is known as the Nash-Moser method. Hörmander, in his paper [10] on the boundaryproblem of physical geodesy, improvedon Moser’s scheme by reducing the … WebWe investigate the local regularity of pointed spacetimes, that is, time-oriented Lorentzian manifolds in which a point and a future-oriented, unit timelike vector (an observer) are selected. Our main result covers the class of Einstein vacuum spacetimes. Under curvature and injectivity bounds only, we establish the existence of a local coordinate chart defined …
Webhas been resolved independently by Nash in 1958 [32]. It was shown later by Moser that the result of De Giorgi and Nash can be obtained using a different formulation [31]. In the literature, this method is often called the De Giorgi-Nash-Moser theory. Let R:= (−∞,+∞), Ω ⊂ Rn(n ≥ 1) be an open bounded set, and γ be a constant.
