### SMS Essay Competition 2021

#### “Mathematics and Pandemics”

- The Singapore Mathematical Society will carry on with the Series in the Application of Mathematics in order to encourage students to explore and discover different facets of Mathematics in our everyday life. We have chosen “Mathematics and Pandemics” to be the theme of the competition this year.
- The ongoing COVID-19 outbreak has highlighted the importance of mathematics in fighting pandemics. Throughout history, a growing corpus of mathematical models has always been used to inform and guide pandemic responses, but never more so than in recent years. There’s never been a better time than now to motivate students to learn about the mathematics applied in disaster management, public healthcare and biomedical science.
- We hope that through this competition, students will discover the different types of mathematical models for its corresponding pandemic response purpose. This includes deterministic models, empirical models, and simulation models. They will understand how mathematics is applied through the modelling process in constructing effective model for informing health policy and increasing the efficiency in screening and tracing. Some examples of these mathematical tools are Differential Equations, Linear Algebra, Probability, Statistics, Discrete Mathematics, Graph Theory, Regression, Multivariate Calculus, Gradient Algorithms, Optimization, Markov Chain, Transition Matrices, etc., which clearly offers diverse topics for the students to explore.
