DESCRIPTION:Lagrangians are half-dimensional submanifolds of symplectic sp
 aces on which the symplectic form vanishes. They are of considerable impor
 tance in symplectic geometry and the study of their equivalence classes dr
 ives much progress in the subject. In this talk\, we will consider various
  notions of equivalence\, which have distinct granularity in general. I wi
 ll present several examples\, mostly in dimension 4\, including some sympl
 ectic phenomena\, and cases where full classifications are achievable. Tim
 e permitting\, I will also introduce symplectic Lefschetz fibrations\, the
 ir links to Lagrangians and also to my own work.
