That’s easy to say, but where does precision really come from? In a word, rigidity. Machine tools do a seemingly magical thing. They remove quantities of steel (or other materials medieval ...

Symptoms such as bradykinesia and tremor can be objectively quantified; however, rigidity is difficult to assess as the origin and nature of this symptom is unclear. A new study has shown that ...

The overall objective of our research programme can be summarised as follows: Develop geometry as a subject and as a powerful tool in theoretical mathematics focusing on the dichotomy of deformations ...

In the middle of the last century, after hearing a talk of Mostow on one of his rigidity theorems, Borel conjectured in a letter to Serre a purely topological version of rigidity for aspherical ...
