The aim of this lecture is to familiarize the students with the basic language of and some fundamental theorems for mapping class groups of surfaces. This course is a continuation of [MTH.B503 : Advanced topics in Geometry G].
Students are expected to
・understand proofs of fundamental theorems on Lefschetz fibrations.
Charts, fiber sums, stabilizations, Kirby diagrams, monodromy substitutions, rational blowdowns, holomorphicity, Stein surfaces.
✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | Practical and/or problem-solving skills |
