Abstract
Tits polygons are generalizations of Moufang polygons. Examples of Tits polygons arise from spherical Moufang buildings by a procedure that involves a Tits index. It is an open question whether each Tits polygon can be obtained in this way. In my talk I will introduce Tits polygons, discuss their motivation and report on our ongoing efforts to answer the above question. This is joint work with Richard Weiss.
