| Abstract: | In this paper,the concepts of the dual space and the transposed mapping in linear algebra were enunciated,which were not well known by physicists. Based on the proposed concepts,two kinds of vectors named as contravariant vector and covariant vector for the general linear group and their transformation laws were fully explained and illustrated. |
