Partial Duality for Ribbon Graphs
摘要
This is an expository paper extending the tutorial talk at the MATRIX Workshop on Uniqueness and Discernment in Graph Polynomials in October 2023. The explanation is mainly based on (S. Chmutov, F. Vignes-Tourneret, Partial Duality of Hypermaps. Arnold Mathematical Journal, 1–24 (2022) doi:s40598-021–00,194-8) with maximal possible simplifications.
