These problems are ubiquitous in our physical world, but also human-made systems are based on this principle: Gradient flows are the workhorse of today's machine learning algorithms. After an introduction in the finite-dimensional setting (giving rise to systems of ordinary differential equations), this course builds up the general theory for gradient flows. Then we will address a selection of problems from physics and data science that can (almost) be put into this abstract framework. Along the way, we will also familiarize ourselves with basic themes of modern analysis like Gamma-convergence and some aspects of optimal transport. Literature Lecture notes will be provided.
