摘要:

通过选取合适的测试函数, 利用二次函数取最值的方法, 证明了与Grushin型算子相关
的退化椭圆算子的精确Hardy不等式, 并给出若干引理. 推广了现有文献中的结果.

Abstract: A generalized sharp Hardy inequality to the degenerate elliptic operators with respect to
Grushin type operators is proved by an ingeniously choosing of test functions and calculating
of the maximum value of a quadratic equation. Some interesting corollaries are also listed.

Key words: degenerate equation, Grushin type operator, sharp Hardy inequality.
