Abstract:We present recent work for constructing multiple nodal solutions having componentwisely-shared nodal numbers of coupled elliptic systems. This is done by further developing critical point theory with built-in flow invariance which has been a useful tool to give locations of critical points by minimum methods. We briefly survey the methods in general. We use the parabolic flow as a deformation combining with minimax methods via a Z_p index theory.
