The Scientific Committee and the Steering Committee are the two principal committees of the Hang Lung Mathematics Awards. The Scientific Committee, comprising world-renowned mathematicians, is the academic and adjudicating body of the Awards. The Steering Committee, comprising mathematicians and representatives from different sectors of society, serves as the advisory body.
The Scientific Committee upholds the academic standard and integrity of Hang Lung Mathematics Awards. Its members actively participate in the evaluation of all project reports, determination of the teams that will be invited to the oral defense, and adjudication at the oral defense.
The Screening Panel under the Scientific Committee handles the initial review of each report, supervises the second and final round of the review process, and liaises with all referees and members of the Scientific Committee regarding the project reports.

Topic | Investigation of the Erdös-Straus Conjecture |
Team Members | Yuk Lun Fong |
Teacher | Mr. Kwok Kei Chang |
School | Buddhist Sin Tak College |
Abstract |
In this paper, we are going to investigate the ${\bf{\textit{Erdős-Straus Conjecture }}}$: For any positive $n \geq 2$, there exists positive integers $k,k_1,k_2$ such that Firstly, we will solve a simpler form $ \dfrac{3}{n} = \dfrac{1}{x} + \dfrac{1}{y}$ as a starting point. Next we will investigate the Erdos-Straus Conjecture in the following dimensions: the related geometric representation of the Erdos-Straus Conjecture, the properties of solutions of the Erdos-Straus Conjecture, further investigation of some paper of the Erdos-Straus Conjecture, existence of special forms of solutions of the Erdos-Straus Conjecture, and the investigation of the Erdos-Straus Conjecture in algebraic dimension. The aim of this report is to find evidence that shows the ${\bf{\textit{Erdős-Straus Conjecture}}}$ is true. If evidence is not strong enough, we still hope that this report can make an improvement to the researched result at present. |
Topic | Pseudo Pythagorean Triples Generator for Perpendicular Median Triangles |
Team Members | Yan Lam Fan, Wai Pan Yik |
Teacher | Mr. Ho Fung Lee |
School | Pui Ching Middle School |
Abstract | The problem of finding all integral sides and lengths of a right-angled triangle is famous and the solution set is called the Pythagorean Triple. Now, instead of the sides of a triangle, we concern ourselves with the orthogonality of lines from vertices to their opposite sides. We want to generalize the problem to the arbitrary rational ratio on the sides. |
Topic | Probability, Matrices, Colouring and Hypergraphs |
Team Members | Hok Kan Yu, Dave Lei, Ka Chun Wong, Sin Cheung Tang |
Teacher | Mr. Yan Ching Chan |
School | P.L.K. Centenary Li Shiu Chung Memorial College |
Abstract | In this project, we achieved various results using Probabilistic Methods. By exploiting the concept of probability and expected value, we managed to achieve three results: distribution of entries on a cube, colouring of vertices of a hypergraph and a lower bound of a maximal independent set on a hypergraph. |
Topic | Classification of Prime Numbers by Prime Number Trees |

Teacher | Mr. Alexander Kin Chit O |
School | G.T. (Ellen Yeung) College |
Abstract | The traditional sieve of Eratosthenes gives a simple algorithm for finding all prime numbers. However, prime numbers seem to appear unpredictably but with regular population ratio in the ranges of integers, as Gauss had found a density function of prime numbers within a range of x. On the other hand, there are few methods of classification of prime numbers. We developed a new classification of prime numbers by prime number trees. In the prime number trees, the following number is generated by attaching a digit either 1, 3, 7, or 9 to the right hand side of the preceding prime number. If the number generated remains a prime, then the process continues, otherwise it stops. The prime number trees group prime numbers with similar digits together and show the elegance of a shorthand of prime numbers. This method also shows a regular classification of prime numbers. |
Topic | Two Methods for Investigating the Generalized Tic-Tac-Toe |
Team Members | Kam Chuen Tung, Luke Lut Yin Lau |
Teacher | Ms. Mee Lin Luk |
School | La Salle College |
Abstract | In this paper, we look into the (m,n,k,p,q) game, one of the generalizations of the well-known Tic-Tac-Toe game. The objective of the game is to achieve ‘k-in-a-row’ with one’s pieces before one’s opponent does. We use two methods – exhaustion and pairing strategy – to investigate the results of the (m,n,k,p,q) game for several different values of the five parameters. |
Topic | A General Formula to Check the Divisibility by All Odd Divisors and its Extensions |
Team Members | Chun Kit Du, Tung Him Lam, Hok Leung Chan, Chi Ming Ng, Kai Yin Ng |
Teacher | Mr. Kwok Tai Wong |
School | S.K.H. Lam Woo Memorial Secondary School |
Abstract | The paper places much emphasis on the method of checking, without using division, the divisibility of an integer by an odd divisor. In part A, it mainly focuses on getting the general way to perform the divisibility test by an algorithm using the unit digit and the rest of the truncated digits of the dividend. Parts B and C are extensions of part A. In part B, it attaches importance to using the last two or more digits of the dividend and so the divisibility test is not just restricted to the ones digit. While parts A and B focus on the method of verifying the divisibility of a number, part C mainly concentrates on finding the quotient without performing division algorithm. This unique method of division is discovered in the process of investigation in part A. |

Team Members | Chi Cheuk Tsang, Ho Lung Tsui, Justin Chi Ho Chan Tang, Ian Yu Young Kwan |
Teacher | Mr. Perrick King Bor Ching |
School | St. Joseph’s College |
Abstract | This study centers on the Euclidean construction of triangles under several given pre-conditions, and carries out several major objectives surrounding this aim: 1. to devise a scheme to primarily distinguish cases in which Euclidean construction is impossible; 2. to seek the simplest agenda in the construction of possible cases; 3. to give a strict definition of Euclidean constructability; and 4. to determine the methods and rigorous proofs of inconstructability. |
Topic | The Application of Graph Theory to Sudoku |
Team Members | Josephine Yik Chong Leung, Wai Shan Lui |
Teacher | Mr. Tad Ming Lee |
School | Ying Wa Girls’ School |
Abstract | In this project, we establish the Sudoku graph by studying the relationship between Sudoku and graphs with the help of NEPS (Non-complete Extended P-Sum). The approach is to look for the chromatic polynomial of the Sudoku graph, so that we can determine the total number of possible solved Sudoku puzzles. Although the chromatic polynomial of the Sudoku graph is not presented in this research, we have found some properties of the polynomial that may provide inspirations for further research. |
