Invariants And Pictures: Low-dimensional Topology And Combinatorial Group Theory: 66 (Series on Knots & Everything)

This book contains an in-depth overview of the current state of the recently emerged and rapidly growing theory of Gnk groups picture-valued invariants and braids for arbitrary manifolds. Equivalence relations arising in low-dimensional topology and combinatorial group theory inevitably lead to the study of invariants and good invariants should be strong and apparent. An interesting case of such invariants is picture-valued invariants whose values are not algebraic objects but geometrical constr...See More
