Limits of tangent spaces to definable sets
Speaker: Đinh Sĩ Tiệp

Time: 9:30 - 10:30, Wednesday December 15, 2021

Abstract: We study the set of tangent limits at a given point to a set definable in any o-minimal structure by characterizing the set of ``exceptional rays'' in the tangent cone to the set at that point and investigating the set of tangent limits along these rays. Several criteria for determining ``exceptional rays'' will be given. (joint work with Olivier Le Gal and Phạm Tiến Sơn).
