本文研究了WT2类微分形式的问题.利用微分形式技巧,得到其Caccioppoli不等式.作为应用,得到拟正则映射的Caccioppoli不等式及高阶可积性,推广了T.Iwaniec等人的结果.
The definition of WT2-differential forms is given. By using the technique of differential forms, the Caccioppoli inequality is obtained. As applications, the Caccioppoli inequality and higher integrability results for quasiregular mappings are derived and some results due to T. Iwaniec et al. are generalized.
