DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/188/">To
 ric and tropical Bertini theorems in arbitrary characteristic</a>\nby Dian
 e Maclagan (University of Warwick) as part of ZAG (Zoom Algebraic Geometry
 ) seminar\n\n\nAbstract\nThe classical Bertini theorem on irreducibility w
 hen intersecting by hyperplanes is a standard part of the algebraic geomet
 ry toolkit. This was generalised recently\, in characteristic zero\, by Fu
 chs\, Mantova\, and Zannier to a toric Bertini theorem for subvarieties of
  an algebraic torus\, with hyperplanes replaced by subtori. I will discuss
  joint work with Gandini\, Hering\, Mohammadi\, Rajchgot\, Wheeler\, and Y
 u in which we give a different proof of this theorem that removes the char
 acteristic assumption. An application is a tropical Bertini theorem.\n
