Mathematics is the language of science. It forms the foundation for various disciplines, such as artificial intelligence, computer science, data science, economics, engineering, physics, and even social sciences. Learning mathematics develops our ability of logical reasoning, precision, critical thinking, such that we can organize and analyze complex information, tackle complex problems in many different areas of your life and career. The programme provides students with a strong background of mathematical theory, skills and tools for mathematical modelling, scientific computation and technical computer software. Our graduates are in high demand in many sectors, including finance, technology, education, etc.. 

The Department specialises in applied and computational mathematics. Undergraduate teaching is backed up by extensive research on a wide range of topics. This places us in close contact with many modern uses of mathematics. Our programme is both relevant and up-to-date.

We are proud of our academic staff, many of whom are internationally renowned scholars. For example, Professor Philippe G. Ciarlet, member of the French Academy of Sciences and of seven other academies, was Chair Professor of the Department until August 2011. He joined the office of the College of Science and Engineering in September 2011 as University Distinguished Professor. Professor Ciarlet has received numerous distinctions, among which a Grand Prize of the French Academy of Sciences and an Alexander von Humboldt Research Award.

Professor Ciarlet is currently Emeritus Professor of the Department, and Senior Fellow in the Institute for Advanced Study of City University of Hong Kong.

本系的教員令我們深感自豪，當中不乏享譽國際的學者。法國科學院兼另外七間學院院士Philippe G. Ciarlet 教授，曾任本系講座教授至二零一一年八月，九月開始出任科學及工程學院大學傑出教授。Ciarlet 教授獲頒多個獎項，其中包括法國科學院的法國科學大獎及洪堡研究獎。

Ciarlet 教授現為香港城巿大學數學系的榮休教授，高等研究院資深院士。

We aim at equipping students and producing graduates with strong backgrounds in data analysis, mathematical modelling, scientific computing and technical computer software. Students are trained to think quantitatively and analyse problems critically.  Our graduates contribute to the commercial, financial and industrial sectors in Hong Kong and throughout Greater China. The programme focuses on linking the applied areas of mathematics and computing.

The Bachelor of Science in Computing Mathematics programme was introduced in 1994. This major is unique in Hong Kong.  It emphasizes the balance between theories and their applications to practical problems, with a special focus on applied mathematics linked to computational aspects.

The major aims at equipping students and producing graduates with a strong background in:

• data analysis
• mathematical modelling
• scientific computing
• technical computer software

Students are trained to think quantitatively and analyse problems critically.

As graduates of our programme, they are in hot demand in a number of fields, including data analysis, business intelligence analysis, mathematical modelling, quantitative business planning, and scientific programming. There is also a demand for mathematics teachers in Hong Kong secondary schools.  Most graduates entered the workforce in business, finance and education sectors.

Apart from joining the workforce, some of our graduates further their studies locally or in overseas universities, such as University of Cambridge and University of Oxford in UK, University of Toronto in Canada, Harvard University, Yale University, New York University, University of Chicago and Universities of California in the US, and ETH Zurich in Switzerland.

計算數學理學士課程於一九九四年開辦，著重理論和應用數學的平衡，尤其是與科學計算之關連。本課程旨在為學生在數據分析、數學模型、科學計算及專業軟件方面建立鞏固的學術根基，並提供數量思考與分析解難能力的培訓。畢業生為各行各業羅致的對象，包括數據分析、數學模型、科學程式編排、數學科教師等。大部份畢業生於商界、金融界或教育界開展事業。

除了開展職業生涯，部份畢業生在本地或海外繼續升學，例如：英國劍橋大學及牛津大學、加拿大多倫多大學，美國哈佛大學、耶魯大學、紐約大學、芝加哥大學及加州大學，以及瑞士蘇黎世聯邦理工學院等。

Students are required to complete 121 credit units in different courses. The major covers communication skills, general studies, and core subjects in Complex Analysis, Computing and Programming Techniques, Differential Equations, Discrete Mathematics, Linear Algebra, Mathematical Analysis, Numerical Methods, Optimization, Ordinary Differential Equations, Partial Differential Equations, and Probability and Statistics.

Electives include Actuarial Science, Applied Functional Analysis, Applied Statistics, Computational Geometry, Dynamical Systems and Chaos, Finite Element Method, Introduction to Stochastic Processes, Mathematical Finance, Modelling and Partial Differential Equations, and Sampling Survey Methods for Social and Market Research.

Students also need to satisfy the university requirements in language and Chinese civilization.  The curriculum is very flexible.  The university requirement for gateway education and free electives give students opportunities to develop their own interests in other subjects.

Please visit the ‘Undergraduate Catalogue’ for the programme’s curriculum structure details.

As a graduate of our major, you will find yourself in hot demand in a number of fields, including data analysis, business intelligence analysis, mathematical modelling, quantitative business planning, and scientific programming. There is also a demand for mathematics teachers in Hong Kong secondary schools. Most graduates entered the workforce in business, finance and education sectors.

The College of Science (CSCI) and the Department offer work placement opportunities through various internship schemes that provide students with full-time job attachments in firms not only in Hong Kong, but also in the Pearl River Delta region and overseas. Through such placements, students will:

• broaden their experience and enhance their employability;
• develop problem-solving abilities and interpersonal skills;
• gain solid experience in a real-world work environment; and
• learn the right attitudes towards work and professionalism.

For details, please visit the College of Science’s internship schemes website.

Furthermore, for students to broaden their educational horizons, gain language experience and enhance their awareness of different cultures, the Department, College and University offer over 110 credit-bearing exchange programmes with various partner institutions around the world, including universities in Australia, Canada, Europe, the US and the Asia-Pacific region.

For details, please visit the University's outbound exchange programme website.

BSc Computing Mathematics students are eligible to apply for the following joint degree programme:
