Prerequisite
The elementary theory about algebraic topology
Abstract
In applied mathematics, topological based data analysis (TDA) is an approach to the analysis of datasets using techniques from topology. In this course we will concentrate mainly on two such techniques: persistent homology and GLMY-homology. Persistent homology is an algebraic tool for measuring topological features of shapes and functions. It casts the multi-scale organization of data into a topological formalism. In our lectures we will give some exposition of mathematical theory and show some applications in biology. Prof Yau and his collaborators introduced the new topology theory (GLMY theory) of digraph in 2012,this theory takes more abstract graph structured data as the research target,developed GLMY homology, hypergraph homology，etc. The relevant theory of this homology has been very rich, and its application has achieved good results in many fields.This course mainly sorts out GLMY homology to help students become familiar with and master the theory.
