Part II of a series of live presentations developing what Riemann actually did with his work on Abelian functions. In this presentation, we refresh the idea of non-quantitative changes developed in Part I, and briefly introduce the nation of the economic field, and topological, as opposed to individual changes. To get at Riemann’s later work on this subject, we deal with a new kind of magnitude that goes beyond “more” and “less” – complex magnitudes.
This video has an accompanying page with additional Q&A and more demonstrations (including interactive ones).
