DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/48/
 ">Toric and tropical Bertini theorems in arbitrary characteristic</a>\nby 
 Diane Maclagan (Warwick) as part of Online Nottingham algebraic geometry s
 eminar\n\n\nAbstract\nThe classical Bertini theorem on irreducibility when
  intersecting by hyperplanes is a standard part of the algebraic geometry 
 toolkit. This was generalised recently\, in characteristic zero\, by Fuchs
 \, Mantova\, and Zannier to a toric Bertini theorem for subvarieties of an
  algebraic torus\, with hyperplanes replaced by subtori. I will discuss jo
 int work with Gandini\, Hering\, Mohammadi\, Rajchgot\, Wheeler\, and Yu i
 n which we give a different proof of this theorem that removes the charact
 eristic assumption.  An application is a tropical Bertini theorem.\n
