DESCRIPTION:Title: <a href="https://researchseminars.org/talk/zorp_1729/1/
 ">Some questions around counting rational points on stacks</a>\nby Jordan 
 Ellenberg (University of Wisconsin–Madison) as part of ZORP (zoom on rat
 ional points)\n\n\nAbstract\nI will talk about a few open questions in ari
 thmetic enumeration which are superficially different but which all arise 
 as special cases of a conjecture of Batyrev-Manin type for algebraic stack
 s formulated by Matt Satriano\, David Zureick-Brown\, and me.  To state th
 e conjecture precisely requires one to say what one means by the height of
  a point on a stack\; some of you have heard me talk about this part befor
 e\, so I am going to attempt to abbreviate that story somewhat and use it 
 as a black box\, focusing instead on some of the geometric challenges of f
 ormulating a counting conjecture\, which we have sort of but not fully sat
 isfyingly surmounted.\n
