Abstract: A random matrix is just a matrix whose entries are random numbers. They appear in many applications, from statistics and quantum physics to signal processing and neuroscience. A central question is: what do the eigenvalues of such matrices look like? Surprisingly, it’s often easier to understand the eigenvalues of very large random matrices than small ones. In this talk, I’ll explain why random matrices matter, and how, despite their randomness, large random matrices often display remarkable regularity.

Abstract: The talk explores how the classical Basis Extension Theorem extends to the setting of free modules through the concept of unimodular elements. It examines when unimodular rows can be extended to invertible matrices, connecting algebraic ideas.

Abstract: The integer partition function p(n) counts the number of ways in which a positive integer n can be written as the sum of positive integers less than or equal to n. For example, 4 can be written as 4, 3+1, 2+2, 2+1+1, 1+1+1+1, so p(4)= 5. In a famous paper written in 1918, Hardy and Ramanujan gave an approximate (asymptotic) formula for p(n). In this talk, we will give an overview of Ramanujan's work and the subsequent developments in understanding the fascinating properties of p(n).

Abstract: An expander family of graphs is a mathematical way of encoding the idea of a "good" network. We will explain what "good" could mean in this context, and use this to define an expander family. We will then describe a way of constructing such families using group theory.

DOCUMENTARY SCREENING: BBC documentary on The Fermat’s Last Theorem: A gripping tale of obsession, genius, and one of the most famous problems in mathematics finally being solved after 350 years. Follow Andrew Wiles as he takes on a mystery that baffled the world for centuries and proves that sometimes, passion really can rewrite history!

Organised an exciting quiz night that took participants on a thrilling journey across the world—connecting geography, history, wars, and sports with the wonders of math and science.

At first glance, it may seem like just another game—but there is an interesting mathematical logic waiting to be uncovered.

This event offers an interactive introduction to Conway’s Game of Life, a classic cellular automaton that illustrates how complex patterns can emerge from simple rules. Participants will explore the unpredictable and mesmerizing behavior of the "game," where cells live, die, or evolve based on their neighbors. No players or traditional strategies required, just observation and discovery. Join us for an engaging evening of emergent complexity, computational beauty, and lively discussion.

This one-of-a-kind event flipped the classic Rubik’s Cube challenge on its head! Instead of solving the cube, participants went head-to-head to scramble a perfectly solved cube into given target patterns—fast. Each round pushed their speed, focus, and precision to the limit as they raced to recreate patterns with flawless accuracy.
