摘要 研究具有加权非线性非局部边界条件的非局部热方程初边值问题中非负解的整体存在和爆破性质。利用上下解的方法找到了边界上的加权函数及非线性指数对解的整体存在性与爆破的影响。 In this paper, we investigate the global existence and blow-up properties of the nonnegative solutions to the initial boundary value problem for a heat equation with weighted nonlinear nonlocal boundary condition. By using the method of upper and lower solution, we obtain some effects of weight function in the boundary condition and nonlinear exponent on the global existence and blow-up solutions.
