The cobordism group of Mِbius manifolds of dimension 1 is trivial

After recalling some general facts about Mِbius structures, we define for any n>0 the cobordism group of Mِbius manifolds of dimension n. We use the classification of Mِbius structures on the oriented S1 to prove that the cobordism group of 1-dimensional Mِbius manifolds is trivial. We also correct an inaccuracy in N. Kuiperʹs classification of projective circles.
