Helge Holden

About

Activities:

[List of publications] I am the chair of the prize committee for the Abel Prize for the period 2023–2026. I am a co-PI on the project IMod – Partial differential equations, statistics and data:
An interdisciplinary approach to data-based modelling. I was the Principal Investigator of the research project ("Toppforsk") Waves and Nonlinear Phenomena (WaNP). I was the Secretary General of the International Mathematical Union (IMU) for the period 2015–2022. On the occasion of my 60th anniversary in 2016 the conference Non-linear PDEs, mathematical physics, and stochastic analysis was hosted here at NTNU. See proceedings Non-Linear Partial Differential Equations, Mathematical Physics, and Stochastic Analysis, European Mathematical Society Publishing House.

Research areas:

Differential equations, mathematical physics; in particular hyperbolic conservation laws and completely integrable systems. Stochastic analysis and flow in porous media.

Teaching:

Fall 2025: TMA4225 Foundations of Analysis

Spring 2025: MA8105 Nonlinear Partial Differential Equations and Sobolev spaces
