Abstract:

Abstract. In my presentation I will give an introduction to numerical

relativity, starting with an elementary discussion of the field equations

of general relativity. I will explain the relevance of PDE theory,

numerical analysis and high-performance-computing to the study of extreme

spacetimes. Afterwards I will discuss progress in the evolution of

gravitational waves that 'just about' collapse to form a black hole. I will

explain why we might expect to see critical phenomena in this regime and

its relevance to the cosmic censorship conjecture.
