ABSTRACT
Thus, we describe common local and global properties of weak compactly supported solutions of nonlinear partial differential equations (PDEs):
(I) 2mth-order quasilinear parabolic PDEs with regional blow-up,
(II) 2mth-order quasilinear hyperbolic PDEs with regional blow-up,
(III) (2m+1)th-order NDEs with TW compactons, and
(IV) 2mth-order quasilinear Schro¨dinger equations with periodic standing wave solutions.
