摘要：We introduce second-order flows as computational model for the solution of problems arising from inverse problems, mathematical imaging and also scientific computing. This is a recent topic inspired by second-order dynamics in convex optimization, while we focus on variational optimization, partial differential equation settings, including non-convex constrained problems. I will present some particular aspects of second-order geometric quasi-linear hyperbolic PDEs along the above lines.
