Existence of multiple solutions for quasilinear diagonal elliptic systems
Electronic journal of differential equations, Tome 1999 (1999)
Nonsmooth-critical-point theory is applied in proving multiplicity results for the quasilinear symmetric elliptic system

$ -\sum_{i,j=1}^{n}D_j(a^{k}_{ij}(x,u)D_iu_k)+ {1\over 2}\sum_{i,j=1}^{n}\sum_{h=1}^N D_{s_k}a^{h}_{ij}(x,u)D_iu_hD_ju_h=g_k(x,u)\,, $

for $k=1,..,N$.
