But except for almost periodic function, others such as asymptotically almost periodic function, weakly almost periodic function and pseudo almost periodic function, theories of relative compactness for those functions are not established.
但是除了概周期函数,其它的例如渐近概周期函数,弱概周期函数,伪概周期函数等概周期型函数集的列紧性理论并未建立,这样使得在某些微分方程的概周期型解存在性理论研究过程中,不动点定理的运用受到了很大的限制,基本都要归结为构造压缩映射。
