Title: Recent results in nonlinear elasticity:  the regularity of energy 
minimisers with positive twist.

Abstract: According to a well-known model due to J. M Ball, the 
behaviour of nonlinearly elastic solids can be understood via properties 
of their energy minimisers.  In this talk we will address the question 
of smoothness of minimisers.  In particular, we will show that when the 
condition of 'positive twist' holds, then in the two-dimensional setting 
energy minimisers are Holder continuous.   We also give a 
characterisation of positive twist in terms of star-shapedness, 
demonstrating that, in principle, it is straightforward to check whether 
a mapping has positive twist or not.
