The basic definitions and operatorsof this theory are given. In the end some grey scale image transformations based on the morphological grey scale image algebra are explained.
By using linear operator theory in L2 space, we proved that the operatorsof this kind has not more than denumerable positive eigenvalues.
运用L2空间上的线性算子理论，我们证明了这类算子存在至多可数个正的本征值。

The infimum and supremum ofoperators, and generalized inverse ofoperators are heated topics in operator theory and also have important value in both theory and application.
