Moufang Loops in Algebra and Geometry I
Abstract:

Moufang loops occur in several areas of mathematics:

  1. As multiplicative structures in a non-desarguesian plane
  2. As the multiplicative structure of the non-zero elements of the Octonions over reals
  3. As the multiplicative structure of points on a cubic hypersurface.
It was Nathan Mendelsohn who first introduced the idea of an "extended triple system" to study the quasigroups arising in various geometric situations including the class of cubic quasigroups (see [2], [4]). Analogous to the case of abelian groups, there is a canonical correspondence between commutative Moufang loops and cubic quasigroups (e.g. see [1]). Motivated by these ideas, here we prove an analog of Manin's theorem for cubic quasigroups. In the coming months, we will explore the connections with Moufang loops and the little Desargues Theorem.
