SUMMARY:Degeneration loci of l-adic local systems - Anna Cadoret (Sorbonne
  Université)
DTSTART:20220620T140000Z

UID:TALK174425@talks.cam.ac.uk
DESCRIPTION:I will make a partial survey of what is expected and known abo
 ut the degeneration loci of l-adic local systems over varieties over numbe
 r fields. For l-adic local systems arising from geometry\, understanding t
 hese degeneration loci is closely related to describing the variation of c
 ertain algebraic-geometric invariants (those encapsulated in l-adic cohomo
 logy) in algebraic families of smooth proper varieties.&nbsp\;&nbsp\;
