Lyapunov-type inequalities for \(n\)-dimensional quasilinear systems

open access: yesElectronic Journal of Differential Equations, 2013
Summary: We prove generalized Lyapunov-type inequalities for a special case of the system \[ -(r_k(x) \phi_{p_k}(u_k'))'= f_k(x) \phi_{\alpha_{kk}}(u_k) \prod^n_{i=1,\,i\neq k} |u_i|^{\alpha_{ki}},\tag{1} \] where \(n\in\mathbb{N}\), \(\phi_\gamma(u)= |u|^{\gamma-2} u\), \(\gamma> 1\), \(r_k\), \(f_k\in C([a,b], \mathbb{R})\), \(r_k(x)> 0\) for \(k= 1 ...
