results in nonlinear elasticity: the regularity of energy
minimisers with positive twist.</div>
<div class="" style="margin: 0cm 0cm 0.0001pt;"><br class="">
</div>
<div class="" style="margin: 0cm 0cm 0.0001pt;">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.</div>
