In line with the Concentration–Compactness Principle due to P.-L. Lions [19], we study the lack of compactness of Sobolev embedding of W1,n(Rn), n?2, into the Orlicz space LΦα determined by the Young function Φα(s) behaving like eα|s|n/(n−1)−1 as |s|→+∞. In the light of this result we also study existence of ground state solutions for a class of quasilinear elliptic problems involving critical growth of the Trudinger–Moser type in the whole space Rn. 相似文献

An affine Moser–Trudinger inequality, which is stronger than the Euclidean Moser–Trudinger inequality, is established. In
this new affine analytic inequality an affine energy of the gradient replaces the standard L
n
energy of gradient. The geometric inequality at the core of the affine Moser–Trudinger inequality is a recently established
affine isoperimetric inequality for convex bodies. Critical use is made of the solution to a normalized version of the L
n
Minkowski Problem. An affine Morrey–Sobolev inequality is also established, where the standard L
p
energy, with p > n, is replaced by the affine energy. 相似文献

We are concerned with the best exponent in Concentration-Compactness principles for the borderline case of the Sobolev inequality. We present a new approach, which both yields a rigorous proof of the relevant principle in the standard case when functions vanishing on the boundary are considered, and enables us to deal with functions with unrestricted boundary values. 相似文献

An important trigonometric inequality essentially due to Wiener but later on made precise by Ingham concerning the lacunary trigonometric sums \(f(x)=\sum A_ke^{in_kx}\), where \(A_k\)’s are complex numbers, \(n_{-k}=-n_k\) and \(\{n_k\}\) satisfies the small gap condition \((n_{k+1}-n_k)\ge q\ge 1\) for \(k=0,1,2,\ldots \), says that if I is any subinterval of \([-\pi ,\pi ]\) of length \(|I|=2\pi (1+\delta )/q>2\pi /q\) then \(\sum |A_k|^2\le A_{\delta }|I|^{-1}\int _I|f|^2\), \(|A_k|\le A_{\delta }|I|^{-1}\int _I|f|\), wherein \(A_{\delta }\) depends only on \(\delta \). Such an inequality is proved here in the setting of the Vilenkin groups G. The inequality is then applied to generalize the Bernstěin, Szász and Ste?hkin type results concerning the absolute convergence of Fourier series on G. 相似文献

On the sharp constant for the weighted Trudinger–Moser type inequality of the scaling invariant form
Michinori Ishiwata Makoto Nakamura Hidemitsu Wadade 《Annales de l'Institut Henri Poincaré (C) Analyse Non Linéaire》2014
In this article, we establish the weighted Trudinger–Moser inequality of the scaling invariant form including its best constant and prove the existence of a maximizer for the associated variational problem. The non-singular case was treated by Adachi and Tanaka (1999) [1] and the existence of a maximizer is a new result even for the non-singular case. We also discuss the relation between the best constants of the weighted Trudinger–Moser inequality and the Caffarelli–Kohn–Nirenberg inequality in the asymptotic sense. 相似文献

The paper raises a question about the optimal critical nonlinearity for the Sobolev space in two dimensions, connected to loss of compactness, and discusses the pertinent concentration compactness framework. We study properties of the improved version of the Trudinger–Moser inequality on the open unit disk ${B\subset\mathbb R^2}$ , recently proved by Mancini and Sandeep [g], (Arxiv 0910.0971). Unlike the original Trudinger–Moser inequality, this inequality is invariant with respect to the Möbius automorphisms of the unit disk, and as such is a closer analogy of the critical nonlinearity ${\int |u|^{2^*}}$ in the higher dimension than the original Trudinger–Moser nonlinearity. 相似文献
