DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GPL/12/">Eul
 er calculus of constructible functions and applications</a>\nby Pierre Sch
 apira (Sorbonne University) as part of Geometry and Physics @ Lisbon\n\n\n
 Abstract\nIn this elementary talk\, we will recall the classical notions o
 f subanalytic sets\, constructible sheaves and constructible functions on 
 a real analytic manifold and explain how to treat such objects “up to in
 finity’”. \n\nNext\, we will describe the Euler calculus of constructi
 ble functions\, in which integration is purely topological\, with applicat
 ions to tomography. Finally we will show how the gamma-topology on a vecto
 r space allows one to embed the space of constructible functions in that o
 f distributions.\n
