加权Dirac算子的Hardy不等式

Hardy inequalities for weighted Dirac operatos

Adimurthi, Kyril Tintarev

摘要:

对Dirac算子和$\R^n$中函数的权$r^{-b}$的二次型建立了一个Hardy型不等式.找到了精确的Hardy常数$c_b=c_b(n)$,并给出了广义极小元.常数$c_b$在$b$的可数集上为零,它推广了已知的$n=2$,$b=0$的情形,$b=0$对应于$\R^2$中的平凡Hardy不等式.类似的不等式证明的情况下,$c_b=0$的约束和误差项,为有界域。

英文摘要:

An inequality of Hardy type is established for quadratic forms involving Dirac operator and a weight $r^{-b}$ for functions in $\R^n$. The exact Hardy constant $c_b=c_b(n)$ is found and generalized minimizers are given. The constant $c_b$ vanishes on a countable set of $b$, which extends the known case $n=2$, $b=0$ which corresponds to the trivial Hardy inequality in $\R^2$. Analogous inequalities are proved in the case $c_b=0$ under constraints and, with error terms, for a bounded domain.
