Quadratic forms playsplay a huge role in math. This leads one to wonder: Is there a theory of cubic forms, quartic forms, quintic forms and so on? I have failed to discover any. Is there any such theory? If not, is it because: It is not as interesting as quadratic forms? It is so hard that no-one has yet written about such a theory? It is already deeply infiltrated in math and only some smart people know about it?
