具有Lipschitz边界的有界域0/RN的哈代不等式断言,| 0| {u| 2个以上|0(x)2,\u #H1 0(0),(1.1)其中+是一个正常数,$(x)= dist(x,0)(见例[7]).式(1.1)中的最佳常数,即+(0)= inf u# H1 0(0)0| {u| 20(美元)2,
Hardy's inequality for a bounded domain 0/RN with Lipschitz boundary asserts that| 0|{u| 2+| 0 (uĀ $) 2,\u# H1 0 (0),(1.1) where+ is a positive constant and $(x)= dist (x, 0)(see eg [7]). The best constant in (1.1), ie+(0)= inf u# H1 0 (0)0|{u| 20 (uĀ $) 2,
