Research Seminar by Prof. Masayoshi Sekiguchi (Kisarazu College, NIT, Japan)

School of Mathematical Sciences will organize a research talk as follows:

Speaker Prof. Masayoshi Sekiguchi (Kisarazu College, NIT, Japan)
Title Double Choreography with Collision to 2N Body Problem
Data Friday, 3 March 2017
Time 11:00 a.m. – 12.00 noon
Venue Conference Room, School of Mathematical Sciences

Title: Double Choreography with Collision to 2N Body Problem


The existence of a double choreography with collisions to 2N Body Problem is shown. I will show an overview of a proof of the existence theorem after giving a brief introduction to N Body Problem with some related topics and a class of periodic solutions: choreography.


- N Body Problem describes the motion of N bodies under the Newtonian law of gravity.
- Choreography is a class of periodic solutions in which N equal masses chase each other along a single closed curve with a common time delay.
- Multiple Choreography is a kind of choreography, but the number of curves is not one. A double choreography to 2N Body Problem has two closed curves which are occupied with N masses for each.

Workshop and Research Seminars by Prof. Michael Dorff

School of Mathematical Sciences will organize workshop and research seminars as follows:

Convenors Dr. Lee See Keong and Prof. Rosihan M. Ali
Speaker Prof. Michael Dorff (Brigham Young University, Utah, USA)
Date 1 - 2 March 2017
Time 10.00 am - 4.30 pm
Venue Conference Room, School of Mathematical Sciences

Workshop: Non-teaching Careers for Mathematicians and Solving Math Problems from Industry.

Date and Time: 1/3/2017 (10.00 - 12.00 noon & 2.30 - 4.30 pm).

Many students and professors think that teaching is the main (or only) career option for someone who studies mathematics. But there are hundreds of jobs for math students. In this workshop, we will discuss some of the exciting things mathematicians in business, industry and government are doing in their careers. We will present some mathematics problems from industry, discuss how these problems are different than the abstract math problems that professors solve, and explore some techniques used in solving these problems.

Seminar: Analytic Functions, Harmonic Functions, and Minimal Surfaces.

Date and Time: 2/3/2017 (9.30 - 10.30 am).

Complex-valued harmonic mappings can be regarded as generalizations of analytic functions and are related to minimal surfaces which are beautiful geometric shapes with intriguing properties. In this talk, we will provide background material about these harmonic mappings, discuss the relationship between them and minimal surfaces, present some new results, and pose a few open problems.

Student Seminar: Soap Bubbles and Mathematics.

Date and Time: 2/3/2017 (11.00 - 12.00 noon).

Venue: DKG 31 School of Mathematical Sciences.

In geometry we learn that the shortest path between two points is a line. In this talk, we explore this idea in several different settings. First, we apply this idea to finding the shortest path connecting four points. Then we move this idea up a dimension and look at a few equivalent ideas in terms of surfaces in 3-dimensional space. Surprisingly, these first two settings are connected through soap films that result when a wire frame is dipped into soap solution. We use a hands-on approach to look at the geometry of some specific soap films and "minimal surfaces".

You are cordially invited to these events. CPD points will be given to USM staff.


The Joint Mathematics Seminar between Universiti Sains Malaysia (USM) and Universiti Malaysia Terengganu (UMT) was held on 17th February 2017. This seminar is an inaugural collaboration between postgraduate students from the School of Mathematical Sciences, USM and School of Informatics and Applied Mathematics, UMT. The meeting kicked off with welcome remarks from the Dean of School of Mathematical Sciences, Prof. Dr. Hailiza Kamarulhaili. In her opening speech, Prof. Hailiza presented the 5 pillars of HEBAT graduate-branding program, which refer to Holistic, Entrepreneurial, Balanced, Articulate and Thinker. She also shared about the courses offered by the School of Mathematical Sciences, USM. Then, the UMT representative, Assoc. Prof. Dr. Roslan Hasni also shared with seminar participants the brief history of the School of Informatics and Applied Mathematics, UMT and some recent developments in mathematical research.

The seminar then proceeded with a fascinating keynote lecture given by Assoc. Prof. Dr. Teh Su Yean. The lecture was entitled “Making Connections through Mathematical Modeling”. This was followed by interesting presentations by 12 postgraduate students from USM and UMT. This year we had an exciting range of presenters ranging from talks on mathematical research to discussion on economic growth. Overall, seminar participants enjoyed a productive day filled with great talks, delicious food and various opportunities to communicate and network. This seminar also provided a platform for the postgraduate students from both universities to present their research, and enabled them to experience the process of communicating and receiving comments in a better professional environment. The organizing committee would like to thank all the speakers for their presentations and all attendees for their active participation and fruitful discussions.
