DESCRIPTION:A classical problem in mathematics is the determination of the
minimal surface that spans a given contour\, which can be realized in the
laboratory as a soap film supported by a wire frame. In the early 1940s R
ichard Courant pointed out nontrivial situations in which a small deformat
ion of certain frames can render unstable the supported surface\, leading
by a rapid dynamical process to a new minimal surface. For example\, a soa
p film Möbius strip can transition to a disc. Despite the enormous body o
f work on the mathematics of minimal surfaces themselves\, the understandi
ng of these dynamical problems is at a very early stage. In this talk I wi
ll summarize our recent experimental and theoretical work on problems of t
his type\, in which a combination of high-speed imaging and stability theo
ry has revealed new insights. (Work done in collaboration with A.I. Pesci\
, H.K. Moffatt\, T. Machon and G.P. Alexander)\n\nhttps://indico.math.cnrs
