Explore our content on a long-standing problem in topology that has only recently been solved.
Want to expand your horizon? Then discover one of the hardest problems in algebraic topology which has only recently been solved: the Kervaire invariant problem.
Zhouli Xu takes us on a trip into higher dimensions, retracing some of the journey towards a proof of the Kervaire invariant problem.
We continue our journey towards a proof of the Kervaire invariant problem.
We explore a famous problem which shaped 20th century topology.
We can't visualise it, but we can still think about it! And there are clever ways of glimpsing what it might look like.
Find out what it means for a shape to have fractional dimension.
We look at an important recent result exploring higher-dimensional holes in higher-dimensional spheres.
We guide you through an exciting recent breakthrough in the world of topology, involving something called the telescope conjecture.
In normal life higher dimensions smack of science fiction, but in mathematics they are nothing out of the ordinary.
