Circulation Theory II

In this part of the talk, I discuss by examples how local asymmetry may add up to the zero total circulation i.e. why do we need functions as opposed to just indices, and how time symmetric processes may still have nonzero circulation in difference - the so called 'sharpness effect'. Applications in logic and categories are discussed.
