Abstract

Consider vector space over non-commutative division algebra. Set of automorphisms of this vector space is group GLGL. Group GLGL acts on the set of bases of vector space (basis manifold) single transitive and generates active representation. Twin representation on basis manifold is called passive representation. There is no automorphism associated with passive transformation. However passive transformation generates transformation of coordinates of vector with respect to basis. If we consider homomorphism of vector space VV into vector space WW, then we can learn how passive transformation in vector space VV generates transformation of coordinates of vector in vector space WW. Vector in vector space WW is called geometric object in vector space VV. Covariance principle states that geometric object does not depend on the choice of basis. I considered transformation of coordinates of vector and polylinear map.
