A Century of Trefftz Methods

Trefftz methods are numerical techniques for solving differential equations using basis functions that satisfy the underlying equations. This tailored approach often leads to higher efficiency compared to traditional methods.

Marking 100 years since Erich Trefftz’s 1926 seminal paper, this workshop will celebrate a centenary of Trefftz methods and look ahead to the future of Trefftz-inspired research.

The workshop is jointly organized by Christoph Lehrenfeld (University of Göttingen) and Paul Stocker (University of Vienna).

Previous Trefftz workshop was held in 2024 · Oaxaca, Mexico.
