Wenqi Liu · Mohu xitong yu shuxue · 2001
This paper studies the relationships between measurable space and Pawlakean algebra by upper(lower) approximate operator defined by measurable sets. It is pointed out that any measurable set is definable set. Any measurable space (U,A) can be spanned to (U,A *) satisfying A t∈A *(t∈T), ∪t∈TA t∈A *. So the main results in paper are proper generally.
