Approximation in the extended functional tensor train format
Christoph Strössner, Bonan Sun, Daniel Kressner
This work proposes the extended functional tensor train (EFTT) format for compressing and working with multivariate functions on tensor product domains. Our compression algorithm c…
Tensor approximation of the self-diffusion matrix of tagged particle processes
Jad Dabaghi, Virginie Ehrlacher, Christoph Strössner
The objective of this paper is to investigate a new numerical method for the approximation of the self-diffusion matrix of a tagged particle process defined on a grid. While standa…
Low-rank tensor approximations for solving multi-marginal optimal transport problems
Christoph Strössner, Daniel Kressner
By adding entropic regularization, multi-marginal optimal transport problems can be transformed into tensor scaling problems, which can be solved numerically using the multi-margin…
Fast global spectral methods for three-dimensional partial differential equations
Christoph Strössner, Daniel Kressner
Global spectral methods offer the potential to compute solutions of partial differential equations numerically to very high accuracy. In this work, we develop a novel global spectr…
