Instead of considering just a string 3-manifold M, one considers a string 3-manifold M endowed with some additional structure Υ. This structure should be such that any M admits at least one Υ. To the pair (M,Υ) there could be associated canonical 3-form ω M,Υ such that R M ω WebPontryagin-Thom construction. Cobordism intersection forms are used to classify compact surfaces; their quadratic enhancements are developed and applied to studying the homotopy groups of spheres, the bordism group of immersed surfaces in a 3-manifold, and congruences mod 16 for the signature of intersection forms of 4-manifolds. ec electronic commerce におけるb to cに該当するものはどれか。
