Degeneration loci of l-adic local systems

speaker: Anna Cadoret (Institut de Mathématiques de Jussieu-Paris Rive Gauche)

abstract: I will make a partial survey of what is expected and known about the degeneration loci of l-adic local systems over varieties over number fields. For l-adic local systems arising from geometry, understanding these degeneration loci is closely related to describing the variation of certain algebraic-geometric invariants (those encapsulated in l-adic cohomology) in algebraic families of smooth proper varieties.
