for all and all , where and are the complex conjugates of and respectively. The composition of two antilinear maps is complex-linear. The class of semilinear maps generalizes the class of antilinear maps.
Antilinear maps occur in quantum mechanics in the study of time reversal and in spinor calculus, where it is customary to replace the bars over the basis vectors and the components of geometric objects by dots put above the indices.
