摘要
利用非紧性测度的性质与凝聚场拓扑度理论,在一般Banach空间中,获得了二阶周期边值问题解的存在与唯一性结果.
The existence problem of second order periodic boundary value problems in general Banach spaces is discussed. By using the theory of noncompactness measure and topological degree of condensing map, some existence and uniqueness results of these problems are obtained.
