Hang Fu
Hang Fu (National Taiwan University) visited Laboratory of Algebraic Geometry in August and September 2018.
On August 24th 2018 Hang Fu gave a talk "Projectively equivalence for the roots of unity" at the seminar of Laboratory.
Abstract:
Let μ ∞ ⊆ C be the collection of roots of unity. Two n-tuples (s 1,···,s n ),(t 1,···,t n ) ∈ μ n ∞ are said to be projectively equivalent if there exists γ ∈ PGL(2,C) such that γ (s i ) = t i for any 1 ≤ i ≤ n.
This talk will discuss the classification of such equivalent pairs.
