This paper deals with the global existence and blow-up of solutions to a inhomogeneous pseudo-parabolic equation with initial value u 0 in the Sobolev space H 1 0 (Ω), where Ω ⊂ R n (n ≥ 1 is an integer) is a bounded domain. By using the mountain-pass level d (see (14)), the energy functional J (see (12)) and Nehari function I (see (13)), we decompose the space H 1 0 (Ω) into five parts, and in each part, we show the solutions exist globally or blow up in finite time. Furthermore, we study the decay rates for the global solutions and lifespan (i.e., the upper bound of blow-up time) of the blow-up solutions. Moreover, we give a blow-up result which does not depend on d. By using this theorem, we prove the solution can blow up at arbitrary energy level, i.e. for any M ∈ R, there exists u 0 ∈ H 1 0 (Ω) satisfying J(u 0) = M such that the corresponding solution blows up in finite time.

In this paper, we consider the initial boundary value problem for the fourth order wave equation with nonlinear boundary velocity feedbacks f 1 (uνt), f 2 (ut) and internal source |u| ρ u. Under some geometrical conditions, the existence and uniform decay rates of the solutions are proved even if the nonlinear boundary velocity feedbacks f 1 (uνt), f 2 (ut) have not polynomial growth near the origin respectively. By the combination of the Galerkin approximation, potential well method and a special basis constructed, we first obtain the global existence and uniqueness of regular solutions and weak solutions. In addition, we also investigate the explicit decay rate estimates of the energy, the ideas of which are based on the construction of a special weight function φ(t) (that depends on the behaviors of the functions f 1 (uνt), f 2 (ut) near the origin), nonlinear integral inequality and the Multiplier method.

In this paper, we continue to study the initial boundary value problem of the quasi-linear pseudo-parabolic equation u t-u t-u-div(|∇u| 2q ∇u) = u p which was studied by Peng et al. (Appl. Math. Lett. 56:17-22, 2016), where the blow-up phenomena and the lifespan for the initial energy J(u 0) < 0 were obtained. We establish the finite time blow-up of the solution for the initial data at arbitrary energy level and the lifespan of the blow-up solution. Furthermore, as a product, we obtain the blow-up rate and refine the lifespan when J(u 0) < 0.
