We give decay estimate of energy function by means Nakao's inequality. Furthermore, under some conditions on the given parameters, we study blow up of solutions for a negative initial energy.eninfo:eu-repo/semantics/closedAccessCoupled Quasilinear SystemGlobal ExistenceDecay RateBlow UpArticle262499519WOS:0005402140000202-s2.0-8506768835110.1007/s40590-019-00243-5Q2N/A
