This is 5th International Conference on Dynamics of Differential Equations – in Memory of Jack K. Hale. The series was established through the joint effort of research groups in the dynamics of differential equations across the Americas, Asia, and Europe, with a scientific focus on the advancement and application of dynamical systems generated by differential equations and their discrete analogs. Previous meetings took place at Georgia Tech, Atlanta, USA (2013), CIRM, Luminy, France (2016), Hiroshima University, Hiroshima, Japan (2018), and Fields Institute, Toronto, Canada (2023). Each conference in the series features a distinguished Hale Lecture, honoring the legacy of Prof. Jack K. Hale. Previous Hale Lectures were given by Geneviève Raugel (2013), Peter Poláčik (2016), Hiroshi Matano (2018), and John Mallet-Paret (2023). The 5th Hale lecture will be given by Rafael de la Llave (Georgia Tech, USA). Young researchers are strongly encouraged to participate and present a poster.

Date: May 20, 2026 (Wednesday) at 4PM (UK time) Speaker: Prof. Ben Green, University of Oxford, UK Topic: The polynomial Freiman-Ruzsa conjecture About the Talk: Prof. Ben Green is an internationally renowned mathematician whose work spans additive combinatorics, number theory, and related areas of analysis. He is widely known for groundbreaking contributions such as the Green–Tao theorem on arithmetic progressions in the primes, and has received numerous prestigious awards in recognition of his influence on modern mathematics. In this talk, he will discuss the polynomial Freiman–Ruzsa conjecture, outlining its background, key ideas, and recent resolution, as well as its role in shaping current research in additive combinatorics.

The conference aims to honor the scientific contributions of Nigel Kalton (1946–2010), whose work has profoundly influenced modern Functional Analysis and related fields. The event will gather researchers from around the world to present recent developments connected to Kalton’s ideas and to explore new directions inspired by his work. The program includes sessions on Kalton’s life and contributions, recent advances in his research areas, invited talks by internationally recognized specialists—including Peter Scholze, Gilles Godefroy, Gilles Lancien, and Grzegorz Plebanek—and opportunities for contributed talks and poster presentations.

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.

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 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.

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. Deadline for application: 15 February 2026

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 workshop "Valentia Geometrica 2026" is scheduled for 20-23 April 2026, and the plan is to cover topics on Geometric Analysis in a broad sense, as a crossroad between Differential Geometry, Partial Differential Equations, Calculus of Variations, Geometric Measure Theory, Metric Geometry,... Speakers: Virginia Agostiniani (Trento) Sigurd Angenent (Wisconsin) Giovanni Bellettini (Siena) Maria Colombo (EPFL) Panagiota Daskalopoulos (Columbia) Manuel del Pino (Bath) Guido De Philippis (NYU Courant) Michael Eichmair (Wien) Nicola Gigli (SISSA) Robert Haslhofer (Toronto) Andrea Malchiodi (SNS Pisa) Rafe Mazzeo (Stanford) Andrea Mondino (Oxford) Aaron Naber (Princeton) Felix Schulze (Warwick) Natasa Sesum (Rutgers) Carlo Sinestrari (Tor Vergata) Peter M. Topping (Warwick) Lu Wang (Yale) Ben Weinkove (Northwestern)​ Organizer: Esther Cabezas-Rivas, supported by CIAICO/2023/035.

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.
