内容記述(抄録等)
Left loops and their projective transformations are considered on analytic manifolds. It is shown that there exists a one-to-one correspondence between the isomorphism classes of the images of the abelian Lie group R_n under projective transformations of left loops and the isomorphism classes of real Lie algebras of dimension n (Theorem 1). For any left loop in projective relation with R_n, the correspondence between normal left subloops and ideals of the tangent Lie triple algebra is established (Theorem 2).
