This vital work is both an introduction to, and a survey of singularity theory, in particular, studying singularities by means of differential forms. Here, some ideas and notions that arose in global ...
In this topic, our goal is to utilise and further develop the theory of non-linear PDEs to understand singular phenomena arising in geometry and in the description of the physical world. Particular ...
When black holes merge, what happens inside of them is anybody's guess. Black hole mergers are beautiful — and some of the most violent events in the cosmos. Here's how the process unfolds.
