SUMMARY:Ailsa Keating (University of Cambridge). On symplectic stabilisatio
 ns and mapping classes
DESCRIPTION:Abstract: In real dimension two\, the symplectic mapping  class
  group of a surface agrees with its `classical’ mapping class  group\, w
 hose properties are well-understood. To what extend do these  generalise t
 o higher-dimensions? We consider specific pairs of  symplectic manifolds (
 S\, M)\, where S is a surface\, together with  collections of Lagrangian s
 pheres in S and in M\, say v_1\, …\,v_k and V_1\,  …\,V_k\, that have 
 analogous intersection patterns\, in a sense that we  will make precise. O
 ur main theorem is that any relation between the  Dehn twists in the V_i m
 ust also hold between Dehn twists in the v_i.  Time allowing\, we will giv
 e some corollaries\, such as embeddings of  certain interesting groups int
 o auto-equivalence groups of Fukaya  categories.\n \nfor further details
