LYAPUNOV-TYPE INEQUALITIES FOR NONLINEAR SYSTEMS INVOLVING THE (p1, p2,...,pn)-LAPLACIAN.

We prove some generalized Lyapunov-type inequalities for n-dimensional Dirichlet nonlinear systems. We extend the results obtained by Çakmak and Tiryaki [6] for a parameter 1 < pk < 2. As an application, we obtain lower bounds for the eigenvalues of the corresponding system. [ABSTRACT FROM AUTHOR]
