Hilbert C*-module

Sažetak
We describe the pullback construction in the category of Hilbert C*-modules (with a suitable class of morphisms) in terms of pullbacks of underlying C*-algebras. In the second section the Busby invariant for extensions of Hilbert C*-modules is introduced and it is proved that each extension is uniquely determined, up to isomorphism, by the corresponding Busby map. The induced extensions of the underlying C*-algebras as well as of the corresponding linking algebras are also discussed. The paper ends with a Hilbert C*-module version of a familiar result which states that a C*-algebra is projective if and only if it is corona projective.
