DESCRIPTION:Gromov-Witten theory in genus zero.\n\nIn 2003 Welschinger defi
 ned invariants of real symplectic manifolds of complex dimensions 2 and 3\
 , which count pseudo-holomorphic disks with boundary and interior point co
 nstraints. Since then\, the problem of extending the definition to higher 
 dimensions has attracted much attention. \n	\n	In the talk\, we give backgro
 und on the problem and describe some previous approaches. We then formulat
 e a result generalizing Welschinger's invariants with boundary and interio
 r constraints to all odd (complex) dimensions. The resulting invariants sa
 tisfy a family of equations\, called the WDVV equations. For $mathbb{C}P^n
 $\, these equations allow the computation of all invariants. This is joint
  work with Jake Solomon.\n
