严格奇异算子在$L_p$空间间的内插和外推

Interpolation and extrapolation of strictly singular operators between $L_p$ spaces

Francisco L. Hernández, Evgeny M. Semenov, Pedro Tradacete

摘要:

研究了严格奇异算子在不同$L_p$空间之间的插值和外推性质。为此,分析了$L_p-L_q$空间之间严格奇异非紧算子的结构。除其他事项外,我们澄清严格奇异性和$L$-特征集的操作之间的关系。特别地,将关于紧算子的Krasnoselskii内插定理推广到严格奇异算子类.

英文摘要:

We study the interpolation and extrapolation properties of strictly singular operators between different $L_p$ spaces. To this end, the structure of strictly singular non-compact operators between $L_p-L_q$ spaces is analyzed. Among other things, we clarify the relation between strict singularity and the $L$-characteristic set of an operator. In particular, Krasnoselskii's interpolation theorem for compact operators is extended to the class of strictly singular operators.
