Krahn studied at the
doctoral degree at Göttingen in 1926, with Richard Courant as his advisor,[2] and his habilitation took place at Tartu in 1928. He is co-author of the Rayleigh–Faber–Krahn inequality.[3]
Krahn worked in Estonia, Germany, the United Kingdom, and the United States in the following areas of pure and applied mathematics:
- Differential geometry
- Differential equations
- Bausparmathematik, which is distantly related to insurance mathematics
- Probability theory
- Gas dynamics
- Elasticity theory
