DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BRAG/36/">St
 ability under Fourier-Mukai transforms on elliptic surfaces</a>\nby Cristi
 an Martinez (UNICAMP) as part of Brazilian algebraic geometry seminar\n\n\
 nAbstract\nLet $X$ be a Weierstrass elliptic surface. By moving the polari
 zation towards the fiber direction while keeping the volume of the polariz
 ation fixed\, we can define a notion of limit Bridgeland stability. In thi
 s talk\, we will prove that under certain conditions the relative Fourier-
 -Mukai transform of a slope semistable sheaf is a limit semistable object.
  In the case that the surface has Picard rank two\, a detailed study of th
 e potential Bridgeland walls will provide us with extra numerical conditio
 ns to guarantee that the Fourier--Mukai transform of a 1-dimensional slope
  semistable sheaf is Bridgeland semistable.\n\nZoom Meeting ID: 913 6913 4
