Complex Conjugate Vector Space - Structure of The Conjugate

Structure of The Conjugate

The vector spaces and have the same dimension over the complex numbers and are therefore isomorphic as complex vector spaces. However, there is no natural isomorphism from to . (The map is not an isomorphism, since it is antilinear.)

The double conjugate is naturally isomorphic to, with the isomorphism defined by

Usually the double conjugate of is simply identified with .

Famous quotes containing the words structure of and/or structure:

    I’m a Sunday School teacher, and I’ve always known that the structure of law is founded on the Christian ethic that you shall love the Lord your God and your neighbor as yourself—a very high and perfect standard. We all know the fallibility of man, and the contentions in society, as described by Reinhold Niebuhr and many others, don’t permit us to achieve perfection.
    Jimmy Carter (James Earl Carter, Jr.)

    Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.
    Germaine Greer (b. 1939)
