5. The representation theories of mp - filter which is created by an non - empty set of a implication algebra on a partial ordered set with condition ( c ) are obtained at first . and it ' s proved that the set which contains all mp - filters of a implication algebra x , denoted by mf ( x ) = { f x f is a filter of x } , is a distributive lattice and a complete lattice also in the view of the concept of mp - filter . then the fuzzy filter of a implication algebra is discussed , and the relations between mp - filter and fuzzy filter are obtained
