A legacy in mathematics

He turned curiosity into ideas that endure.

The Arf invariant, Arf rings and the Hasse–Arf theorem remain part of modern mathematics — a body of work that continues to influence how the field is understood.

We carry the ARF name as a standard: rigorous thinking, independent inquiry and a lasting belief in science.
