The 12th KMGS will be held on October 6th, Thursday, at Natural Science Building (E6-1) Room 1501.

We invite a speaker Juhun Baik (백주헌) from the Dept. of Mathematical Sciences, KAIST.

The abstract of the talk is as follows.

Slot (AM 11:50~PM 12:30)**[Speaker]** Juhun Baik (백주헌) from Dept. of Mathematical Sciences, KAIST, supervised by Prof. Hyungryul Baik (백형렬 교수님)**[Title]** Shift locus of cubic polynomial**[Discipline]** Topology**[Abstract]**This talk is about the complex dynamics, which cares the iteration of holomorphic map (usually a rational map on the Riemann sphere), and the shift locus is a nice set of polynomials that all critical points escape to infinity under iteration.Understanding the shape and topology of shift locus is a challenge for decades, and accumulated works are done by Blanchard, Branner, Hubbard, Keen, McMullen, and recently Calegari introduce a nice lamination model.In this talk I will explain the basic complex dynamics and introduce the topology of the shift locus of cubic polynomials done by Calegari’s paper ‘Sausages and Butcher paper’ and if time allows, I will end this talk with the connection to the Big mapping class group, the MCG of Sphere – Cantor set.**[Language]** Korean (English if it is requested)
