Lagrangian Floer homology was introduced by Floer in the 80's in order to prove a conjecture of Arnold about the number of periodic orbits of a Hamiltonian system. Later on, Fukaya conjectured that the simple homotopy type of the Floer complex was a complete invariant of Lagrangian intersection phenomena in symplectic geometry. I will give an overview ot these notions and explain how they are connected to enumerative geometry of holomorphic discs.
