Let E be a Hilbert C*-module,and ■ be an orthogonally complemented closed submodule of E.The authors generalize the definitions of ■-complementability and ■-compatibility for general(adjointable) operators from Hilbert space to Hilbert C*-module,and discuss the relationship between each other.Several equivalent statements about ■-complementability and ■-compatibility,and several representations of Schur complements of ■-complementable operators(especially,of ■-compatible operators and of positive ■-compatible operators) on a Hilbert C*-module are obtained.In addition,the quotient property for Schur complements of matrices is generalized to the quotient property for Schur complements of ■-complementable operators and ■*-complementable operators on a Hilbert C*-module.
