Nevertheless\, in valua tive geometries\, such as Berkovich or adic\, some wild ramification pheno mena that originally look chaotic do get very conceptual explanations. In my talk I will give a few examples with the different function of a ramifi ed covering being the main player.\n\n(At 2 pm in advance\, there will be an informal pre-talk giving an introduction to non-archimedean geometry.)\ n LOCATION:https://researchseminars.org/talk/agstanford/123/ END:VEVENT END:VCALENDAR
