论文摘要
研究了至少三种非线性时间依赖性方程的三种弱解。实际上，我们认为源函数的原点具有奇异性。为此，变异方法和众所周知的关键点定理是主要工具。
The existence of at least three weak solutions for a kind of nonlinear time-dependent equation is studied. In fact, we consider the case that the source function has singularity at origin. To this aim, the variational methods and the well-known critical points theorem are main tools.
