 sité Paris-Sud) as part of IPM Mathematics Colloquium\n\n\nAbstract\nFor 
 over a century de Rham cohomology has played a central role in geometry\, 
 analysis and arithmetic. \nIn positive characteristic\, it is still a myst
 erious object. I will explain recent discoveries about it\, due to \nBhatt
 -Lurie\, Drinfeld\, and Petrov\, in the wake of the theory of prismatic st
 acks.\n\nOnline via BigBlueButton:\n\nhttps://vroom.ui.ac.ir/b/jav-qqx-92n

 thColloq/3/">Perspectives in Scalar Curvature</a>\nby Mikhael Gromov (IHES
 ) as part of IPM Mathematics Colloquium\n\n\nAbstract\nManifolds with thei
 r scalar curvatures bounded from below display flexibility of shapes simil
 ar to what happens in the geometric and in the symplectic topology. The pr
 oblem of evaluating the limits to this flexibility is inseparable from the
  index theory of Dirac operators and the geometric measure theory.\n\nOnli

 thColloq/4/">Vector field on plane in characteristic zero and p>0</a>\nby 
 Valery Lunts (Indiana University) as part of IPM Mathematics Colloquium\n\
 n\nAbstract\nA polynomial vector field on a complex plane C^2  defines a f
 oliation of the plane and one would like to know when the leaves of this f
 oliation are algebraic\, i.e. when the analytic integral curves are algebr
 aic. This is a hard unsolved problem. I will suggest a conjectural approac
 h to this problem which uses the reduction of the vector field modulo prim
 es p. It turns out that the corresponding problem in characteristic p is e
 asy to solve. We then conjecture that the original vector field is algebra
 ic if and only if its reduction modulo a prime p is algebraic for almost a
 ll p. We have some partial results towards proving this conjecture. This i
 s a work in progress with D. Leshchiner.\n\nOnline via zoom:\n\nMeeting ID

 thColloq/5/">New technologies and mathematics</a>\nby Kevin Buzzard (Imper
 ial College London (UK)) as part of IPM Mathematics Colloquium\n\n\nAbstra
 ct\nComputers have been used to do calculations in mathematics for many de
 cades. But in the last few years\, several new ways to use computers to do
  mathematics have appeared. I'll give an overview of these ideas\, explain
  where we are right now\, and suggest where things might be going.\n\nOnli
