The book is important in indicating that the classical theory of electromagnetism, or Maxwell theory, can be developed to address situations and signals of differing symmetry form, and that different topological spaces require that development"-- UR - https://www.worldscientific.com/worldscibooks/10.1142/12755#t=toc ER -
