Alexei Ilyin, Ari Laptev, Sergey Zelik

摘要:

考虑$d$维格上的$l^2$ -数列空间嵌入到$l^\infty_0$空间的插值不等式,记作序列的$l^2$ -范数与其差之间的插值不等式.给出了求这类不等式的尖常数、极值元和修正项的一般方法。应用卡尔森不等式和离散算子的谱理论。

英文摘要:

We consider interpolation inequalities for imbeddings of the $l^2$-sequence spaces over $d$-dimensional lattices into the $l^\infty_0$ spaces written as interpolation inequality between the $l^2$-norm of a sequence and its difference. A general method is developed for finding sharp constants, extremal elements and correction terms in this type of inequalities. Applications to Carlson's inequalities and spectral theory of discrete operators are given.
