PDE-Aware Deep Learning for Inverse Problems in Cardiac Electrophysiology [PDF]

open access: yes, 2022
In this work, we present a PDE-aware deep learning model for the numerical solution to the inverse problem of electrocardiography. The model both leverages data availability and exploits the knowledge of a physically based mathematical model, expressed ...

Image compression with anisotropic diffusion [PDF]

open access: yes, 2008
Compression is an important field of digital image processing where well-engineered methods with high performance exist. Partial differential equations (PDEs), however, have not much been explored in this context so far. In our paper we introduce a novel

Advanced numerical treatment of chemotaxis driven PDEs in mathematical biology [PDF]

open access: yes, 2013
From the first formulation of chemotaxis-driven partial differential equations (PDEs) by Keller and Segel in the 1970's up to the present, much effort has been expended in modelling complex chemotaxis re- lated processes.

Fold-type solution singularities and characteristic varieties of nonlinear PDEs [PDF]

open access: yes, 2009
The concept of generalized (distribution) solutions has been of central importance for the development of the theory of linear PDEs, but it is commonly acknowledged to be inadequate for nonlinear PDEs. In the 70’s A. M.
