Note on the Cobordism Ring

Cobordism is an equivalence relation among compact differentiable manifolds which can be roughly described by: two manifolds are cobordant if together they form the boundary of a differentiable manifold with boundary. Disjoint union and topological product of manifolds induce addition and multiplication operators with respect to which the equivalence classes form a ring graded by dimension. In ...
