分数阶Sobolev范数的注记

Remarks on Sobolev norms of fractional orders

Thanh Tran

摘要:

当一个属于分数阶索伯列夫空间的函数在定义了索伯列夫空间的Lipschitz整环的真子集中得到支撑时,它作为一个函数在较小集合上的索伯列夫范数与它在整个整环上的范数相比如何?比较常数取决于什么?不同的规范是否有不同的表现?本文将讨论这些问题。证明了一些不等式,并通过反例反驳了一些误解。

英文摘要:

When a function belonging to a fractional-order Sobolev space is supported in a proper subset of the Lipschitz domain on which the Sobolev space is defined, how is its Sobolev norm as a function on the smaller set compared to its norm on the whole domain? On what do the comparison constants depend on? Do different norms behave differently? This article addresses these issues. We prove some inequalities and disprove some misconceptions by counter-examples.
