Workshop 1: Flexibility
of Polyhedra and Frameworks
In the last decades outstanding results have increased the
general interest in flexibility and rigidity:
This started 1977 with R. Connelly's construction of a piecewise linear
flexible embedding of the 2sphere into the Euclidean 3space, a
'flexing sphere'.
It was continued 1996 when I. Sabitov presented the first proof of
the famous 'Bellows Conjecture' stating that for every flexible polyhedron
in the Euclidean 3space the volume keeps constant during the flex.
There is still a wide field of open problems left which are motivated
by mathematical reasons.
But this topic is also very important for many engineering applications 
not only for mechanical or constructional engineers, but also for
biologists in protein modelling or for the analysis of isomers in chemistry.
This workshop is dedicated to new questions and results around such
problems.
