Krzysztof Gawędzki is a mathematical physicist. Much of his works is related to conformal field theory, especially geometric aspects of WZNW models. More recently he studies turbulence. He has helped identify the Kalb-Ramond field/B-field with a cocycle in ordinary differential cohomology (in Deligne cohomology/a bundle gerbe with connection).
Pronounciation note: the Polish ‘ę’ (cf. wikipedia) has a nazalization.
On supergeometry and supermanifolds:
On 2d conformal field theory and introducing Deligne cohomology in degree 3 (bundle gerbes with connection) as global models for the background B-field, such as in the WZW model:
