Title: Rigid maps and origami: Dirichlet problem for maps with orthogonal gradient
Abstract: Rigid maps are Lipschitz functions such that the gradient is almost everywhere an orthogonal matrix. A particular case of rigid maps can be described experimentally by means of origami, the japanese art of paper folding. We will show how to construct rigid maps with given boundary data, by means of particular origami constructions.
