我们在离散$L^p$框架下建立基态表示与临界Hardy不等式。特别地,对所有$p\in(1,\infty)$,我们构造了半直线上离散Dirichlet Laplacian与整数上离散分数阶Laplacian的临界Hardy权。我们的方法采用Sobolev-Bregman型,其基态表示为精确恒等式,对应Hardy权通过作用于正超调和函数幂次的线性算子表达。
英文摘要
We establish ground-state representations and critical Hardy inequalities in the discrete $L^p$ setting. In particular, we construct critical Hardy weights for the discrete Dirichlet Laplacian on the half-line and the discrete fractional Laplacian on the integers for all $p\in(1,\infty)$. Our approach uses Sobolev--Bregman forms, for which the ground-state representations are exact identities and the corresponding Hardy weights are expressed through linear operators acting on powers of positive superharmonic functions.
