Publisher Summary Using the notion of complete lift it is shown that G structures as a pseudo-Riemannian structure, an almost complex structure and a symplectic structure on M induce similar structures on the tangent bundle T(M). An unexpected but perhaps more interesting result is that each pseudo-Riemannian (resp. affine) symmetric space structure on M induces a pseudo-Riemannian (resp. affine) symmetric space structure on T(M). This suggests a method of producing a large class of affine symmetric spaces. The chapter considers A be a local algebra of the form A=R+I where R is the field of real numbers and I is the maximal ideal of A such that dim I k =0 for some k. A successful generalization of the theory to A(M) furnishs a useful tool for the differential geometry of higher order contact and yield a large number of affine symmetric spaces.
