Description: Peter Krautzberger speaks on “Idempotent Ultrafilters: An Introduction”.nnAbstract:nnSince the1970s a close relationship has been studied between idempotent ultrafilters and Ramsey-type theorems with an algebraic flavor, most prominently Hindman’s Theorem and the Central Sets Theorem. This connection led to the investigation of the rich algebraic structure that can be found on the ultrafilters on a semigroup.nI hope to begin a conversational introduction into the theory behind these result
