Welcome to The Centre for Combinatorics, Algebra and Number Theory
The Centre for Combinatorics, Algebra and Number Theory (CeCANT) encompasses a broad spectrum of research with a long and distinguished history at Queen Mary. CeCANT includes over 20 academic staff in the School of Mathematical Sciences (SMS). The centre includes a vibrant community of PhD students, fully embedded in our research culture, and has strong research connections with other centres in SMS and beyond.
Within the Faculty of Science and Engineering we align strategically with the Fundamental Discovery Science theme, with the bulk of our research aiming to address fundamental questions in pure mathematics. Our strengths extend to applied mathematical areas, notably game theory in economics and combinatorial optimisation.
