WebBasically, there are two types of lacking the compactness property: Unbounded domains and critical exponents. In both cases, it is more convenient to dilate a "good" function plus a scaling of this function if working in bounded domains. $\endgroup$ – WebDec 13, 2007 · In the critical and subcritical cases (s>=n/2-2/(p-1)>=0), we prove the existence and asymptotic completeness of wave operators in the sense of Sobolev norm …
Webon L2-based critical Sobolev norms imply scattering estimates. As another application of our techniques, we establish a variant which al-lows for slow growth in the critical norm. … Webscaling symmetry, one de nes the scaling-critical Sobolev index s c such that the homogeneous H_ sc-norm is invariant under the dilation symmetry. A simple calculation …
WebOn the one hand, NLW on Rd enjoys the scaling symmetry, which induces the so-called scaling critical Sobolev index: s 1 = d 2 2 k 1. On the other hand, NLW also enjoys the conformal symmetry, which yields its own critical regularity: s 2 = d+1 4 1 k 1. In the one-dimensional case, there is another critical regularity due to lack of dispersion ... WebMay 11, 2024 · There are many exitence results of semilinear elliptic problem with critical sobolev index, for example, the Brezis-Nirenberg problem: $$-\Delta u =\lambda u+u u ^{2^{*}-2}.$$ However, it seems all the results based on a compensated compactness method, which need some translation and scaling invariant property, but how to deal with …

WebApr 15, 2024 · Before reviewing known results for the Cauchy problem (1.1), we recall the critical Sobolev index from which one can divide the matter into three cases. Note first that if u ( x, t) is a solution of (1.1) so is u λ ( x, t) = λ 2 − α β u ( λ x, λ 2 t), with the initial data u λ, 0 ( x) = u λ ( x, 0) for all λ > 0. rounded outdoor seatingWebMar 26, 2024 · Macro placement is a critical very large-scale integration (VLSI) physical design problem that significantly impacts the design powerperformance-area (PPA) … strathavon bed and breakfastWebOne then defines the so-called scaling critical Sobolev index sc:= 1 to be the index sfor which the homogeneous H˙ s(Rd) × H˙ s−1(Rd)-norm of (u(0),∂ tu(0)) is invariant under the scaling (1.3). We notice that the critical space H˙ 1(Rd)×L2(Rd) under the scaling coincides with the energy space E(Rd).

Sobolev norms are trying to measure a combination of three aspects of a function: height (amplitude), width (measure of the support), and frequency (inverse wavelength). Roughly speaking, if a function has amplitude A, is supported on a set of volume V, and has frequency N, then the W k, p norm is going to be about A N k V 1 / p. rounded outWebJun 2, 2015 · Download Citation Blow-up of the critical Sobolev norm for nonscattering radial solutions of supercritical wave equations on $\mathbb{R}^{3}$ We consider the wave equation in space dimension ... rounded out torx boltWebThis is related to my previous question An inequality involving Sobolev embedding with epsilon.
