More specifically, this work addresses geometric problems, such as differential equations on curved spaces or mechanical systems, for which it is essential to ensure that the approximate solutions are physically plausible. The applications discussed range from generating random fields on surfaces to reconstructing protein conformations from noisy microscopy data, all of which are inherently geometric problems.
