Affine invariants of an immersion of a topological space in the n-dimensional real vector space

D. Khadjiev, Sh. Ayupov, İ. Ören

Let ℝ be the field of real numbers and ℝn be the n-dimensional vector space over ℝ, where n>1. Let X be a Tyhonoff topological space and assume that it has at least two elements. For natural actions on ℝn of the group of all non-degenerate linear transformations, the group of all affine transformations and their some subgroups, problems of equivalence f topological immersions of X in ℝn are investigated. Complete systems of global invariants of a topological immersion of X in the space ℝn are obtained for these groups. Complete systems of relations between elements of the complete systems of invariants are investigated.
