论文摘要
我们证明了一些非欧几里得霍尔德空间的真实插值表征,该空间是建立在一类由一类超顺式助型kolmogorov-type型操作员诱导的谎言结构上的,这些操作员满足了Hörmander条件。作为副产品,我们还获得了整个空间上固有规则功能的近似属性。
We prove a real interpolation characterization for some non Euclidean Hölder spaces, built on the Lie structure induced by a class of ultra-parabolic Kolmogorov-type operators satisfying the Hörmander condition. As a by-product we also obtain an approximation property for intrinsically regular functions on the whole space.
