abstract:In mathematics, especially in the area of algebra known as group theory, the Fitting length (or nilpotent length) measures how far a solvable group is from being nilpotent. The concept is named after Hans Fitting, due to his investigations of nilpotent normal subgroups.
It's been replaced with a more sophisticated shoulder-length style more fitting a busy post-retirement career as a wife, a mother of two, an Olympics booster and a motivational speaker.
Many of them sport lungis, a sarong-like cloth wrapped around the waist, instead of kurta-pyjamas, a collarless knee-length shirt worn with loose-fitting trousers.
