Travelling patterns on Discrete Media
This thesis describes how complex and realworld relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or twodimensional lattices.

Studying abstract mathematical equations using tangible surfaces
On January 5, Rosa Winter will obtain her doctorate in arithmetic geometry. She researched solutions of equations that define socalled ‘del Pezzo surfaces’. ‘I like geometry because I can imagine and draw the shapes and objects,’ says Winter. ‘That makes abstract mathematics feel more tangible.’

Exhibition 'The Drake Equation'  online
In Green Bank, Virginia are some giant radio telescopes which astronomers use to study objects deep in space. Because these telescopes are built to capture very faint redio signals, the area around the observatory is officially a 'radioquiet' zone, without WiFi, radio or Cell signal. Photographers…

Plankton and tumours captured in mathematical equations
Plants that grow in patterns of stripes on the edge of deserts, plankton that live on the sea bed or oscillate in the water, and melanomas that spread throughout the body. Mathematician Lotte Sewalt discovered the common elements in these three systems. PhD defence 8 September.

Bayesian Inference for Gaussian Models
This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

Hydrodynamics and the quantum butterfly effect in Black Holes and large N quantum field theories
Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Noisy Patterns: Bridging the gap between stochastics and dynamics
In this thesis, we study travelling waves in stochastic reactiondiffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…

Martin Bright
‘Wild’ might not be the first word that springs to mind when you think about mathematics. But there is, most definitely, a wild side to this research area, consisting of problems that are extremely elusive and difficult to ‘tame’. Martin Bright works on one of these problems. His aim is to tame the…

Modelling the role of cytotoxic T lymphocytes in tumour regression
Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

From wine tears to cloud transport: large mathematical conference in Leiden
The winner of the highest scientific distinction in mathematics, an explanation for wine tears and much more mathematical theory and application. From 8 to 12 July, 550 mathematicians will meet in the center of Leiden to discuss differential equations.

Summer school
In the week of July 1st  5th there will be a summer school on "Data science for dynamical systems" at the Lorentz Center in Leiden.

Koenraad Schalm Group (String Theory and Experiment)
Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Algebra, Geometry and Number Theory
The research of the Algebra, Geometry and Number Theory programme ranges from fundamental mathematical theory to algorithms and applications.

Enumerative arithmetic
This thesis consists of three chapters. Each chapter is on a different subject. However, all three chapters address issues that arise in counting arithmetically interesting objects.

Programme structure
The research specialisation offers you the opportunity to spend two full years on training in applied mathematics to become an independent scientist with a strong theoretical basis.

Quantitative Particle Tracking
Brownian motion is the random motion of (colloidal) particles due to collisions with the atoms and molecules of the solvents, which are moving due to temperature.
