本文研究了加权流形上加权p-Laplacian特征值问题的第一特征值下界估计的问题.利用余面积公式、Cavalieri原理以及Federer-Fleming定理,获得了由Cheeger常数或等周常数确定的第一特征值的下界估计.
In this paper, we estimate the lower bounds of the first eigenvalues for the weighted p-Laplacian on manifolds. By using the coarea formula, the Cavalieri principle and the FedererFleming theorem, we obtain the estimation of the lower bounds for the first eigenvalues by the Cheeger constant or the isoperimetric constant.
