Web5 de jun. de 2012 · An isotopy of a knot can be thought of as a continuous path in this space. Knot invariants are the locally constant functions on K; therefore, the vector space of R-valued invariants, where R is a ring, is the cohomology group H 0 (K, R). We see that the problem of describing all knot invariants can be generalized to the following: Problem.
