Abstract: | ![]() We study the nonlinear eigenvalue problem ![begin{equation*}-text {div }(| nabla u|^{p-2} nabla u)=lambda |u|^{p-2}u quad text {in}; Omega , quad u=0quad text {on}; partial Omega ,tag *{(1) }end{equation*}](http://www.ams.org/proc/1997-125-11/S0002-9939-97-03961-0/gif-abstract/img8.gif)
where , is a bounded smooth domain in . We prove that the first and the second variational eigenvalues of (1) are continuous functions of . Moreover, we obtain the asymptotic behavior of the first eigenvalue as and . |
