Linear algebra MOC Linear isomorphism A π-linear isomorphism π :π βπ is an isomorphism in Category of vector spaces, linalg i.e. a linear map with a (necessarily unique) two-sided inverse πβ1 :π βπ such that πβ1π =1π and ππβ1 =1π. Properties A linear map π βπ΅πΎπΌππ(π,π) is an isomorphism iff it is a linear monomorphism and split linear epimorphism. See Corollaries. tidy | en | SemBr
