Guest Lecture
Besides lectures and tutorials, we also organize guest talks for EPYMT students.
In 2015 summer, we are going to organize the following talks:
1. Guest Lecture on 30 July 2015
| Topic | Random Walks, PageRank, and Computer Science |
| Speaker | Prof. CHAN Siu On
Department of Computer Science and Engineering, CUHK |
| Date | 30 July 2015 (Thur) |
| Time | 2:30pm - 4:00pm |
| Venue | LT7, Lee Shau Kee Building (LSK), The Chinese University of Hong Kong (Map) |
| Abstract | Random walk is a fundamental concept in probability theory. This theoretical concept turns out to have an influential application: it underpins the PageRank algorithm that Google uses to measure webpages' importance. We will explain this connection and introduce the underlying spectral graph theory. We will also mention related challenges in theoretical computer science. |

2. Guest Lecture on 5 August 2015
| Topic | Fun with spheres |
| Speaker | Dr. FOK Chi-Kwong
National Center for Theoretical Sciences, National Taiwan University |
| Date | 5 August 2015 (Wed) |
| Time | 2:30pm - 4:00pm |
| Venue | LT1, Lady Shaw Building (LSB), The Chinese University of Hong Kong (Map) |
| Abstract | Among all closed and bounded surfaces, spheres are the simplest, yet the most symmetrical and occur most frequently in the nature. Since the time of Archimedes, they have been objects of great interest in mathematics. In this talk, we will take a stroll through some fascinating properties of spheres and use them as toy models to get a taste of some far-reaching theories in topology. |

All are welcome. No registration and payment is required. First come first served.
In 2014 summer, we held a guest talk in Ricci Flow and Wallach Space. Many students enjoyed the talks and raised further mathematics questions.
