【 摘 要 】

This article concerns a Kirchhoff-type parabolic problem on a geodesic ball of hyperbolicspace. Firstly, we obtain conditions for finite time blow-up, and for the existence of globalsolutions for J(u_0)≤ d, where J(u0) denotes the initial energy and d denotes the depth of the potential well.Secondly, we estimate the upper and lower bounds of the blow-up time.In addition, we derive the growth rate of the blow-up solution and the decay rate of the global solution.Thirdly, we establish a new finite time blow-up condition which is independent of d and prove that the solution can blow up in finite time with arbitrary high initial energy, by using this blow-up condition.Finally, we present some equivalent conditions for the solution existing globally or blowing upin finite time.
