Date: April 15, 2026 (Wednesday) at 4PM (UK time) Speaker: Prof. Harald Andrés Helfgott, Paris City University, France Topic: Growth, expansion and escape in groups Prof. Harald Helfgott is a leading mathematician who made fundamental contribution to number theory, group theory, and additive combinatorics. He is widely known for his proof of the ternary Goldbach conjecture, as well as for foundational contributions to the study of growth and expansion phenomena in groups. In this talk, he will discuss growth and expansion in groups, including progress toward the celebrated Babai conjecture on the diameters of finite simple groups.

In this seminar leading experts introduce key elements of mathematical knot theory and discuss physical applications, from vortex dynamics to magnetic fields, from polymer physics to proteins and DNA biology. Topics include an introduction to knots, links and braids, knot invariants and related algebraic structures. From knotoids and linkoids to the real world of physical entanglements, the mathematical tools of knot theory become essential to describe natural phenomena around us.

The study of fluid flows on Riemannian manifolds generalizes the classical theory of fluid dynamics in Euclidean space to curved spaces. This extension is motivated both by applications and by intrinsic mathematical interest in the interplay between partial differential equations and differential geometry. Central to this theory is the formulation of the Navier-Stokes equations on a Riemannian manifold, which describe viscous fluid motion subject to the geometry of the underlying space. Some basic questions are: (Formulation) How should the Navier-Stokes equations be correctly expressed on a general Riemannian manifold? (Well-posedness) Do the standard questions of existence, uniqueness, and regularity of solutions extend naturally to manifolds? Deadline for application: 15 February 2026

The Computers in Scientific Discovery (CSD) conference series is designed to bring together researchers whose work makes connections between mathematics, computer science, and natural sciences. In particular, the CSD meetings have concentrated on how algorithms, mathematical software and data are used in non-trivial ways to advance research in the mathematical and physical sciences. The conferences focus not only on applications, but also on mathematical foundations, philosophy and practicalities of the scientific discovery process, including conjecture-making, construction and the use of curated databases of mathematical objects, and computer-aided proofs. The main theme of the 11th CSD conference is ‘Computationally Intensive Methods in Mathematics: Applications in Chemistry and Beyond’. The conference will take place 4–8 May 2026 in picturesque Kranjska Gora, Slovenia.

The 43rd Annual Conference of the Nigerian Mathematical Society is scheduled to hold from May 12–16, 2026. This annual conference brings together mathematicians from across Nigeria, as well as participants from outside the country, to share research ideas and present new findings in various areas of mathematical research. With Akwa Ibom State selected as the host location for the May 2026 edition, the conference is expected to attract a large number of participants.

The field of Analysis in Metric Spaces has experienced remarkable growth over the past three decades and now sits at the crossroads of potential theory, geometric measure theory, geometric function theory, and partial differential equations. Its influence extends to diverse areas such as dynamical systems, geometric group theory, and synthetic differential geometry. Our aim is to gather a vibrant and diverse community of leading experts and emerging researchers to share recent breakthroughs, explore new directions, and foster meaningful collaborations across disciplines.
