This BCAM SpringerBriefs is a treaty of the Infinity-Laplace Equation,
which has inherited many features from the ordinary Laplace Equation,
and is based on lectures by the author. The Infinity-Laplace Equation
has delightful counterparts to the Dirichlet integral, the mean value
property, the Brownian motion, Harnack's inequality, and so on. This
"fully non-linear" equation has applications to image processing and to
mass transfer problems, and it provides optimal Lipschitz extensions of
boundary values.
