Finite-Time Convergence Guarantees for Time-Parallel Methods
Giancarlo Antonino Antonucci, Raphael Andreas Hauser, Debasmita Samaddar +1
Time-parallel algorithms, such as Parareal, are well-understood for linear problems, but their convergence analysis for nonlinear, chaotic systems remains limited. This paper intro…

Local Convergence of Adaptively Regularized Tensor Methods
Karl Welzel, Yang Liu, Raphael A. Hauser +1
Optimization methods that make use of derivatives of the objective function up to order are called tensor methods. Among them, ones that minimize a regularized th-order…
