Arnold–Givental conjecture
The Arnold–Givental conjecture, named after Vladimir Arnold and Alexander Givental, is a statement on Lagrangian submanifolds. It gives a lower bound in terms of the Betti numbers of L on the number of intersection points of L with a Hamiltonian isotopic Lagrangian submanifold which intersects L transversally.
Let Ht ∈ C ∞(M); 0 ≤ t ≤ 1 be a smooth family of Hamiltonian functions of M and denote by φH the time-one map of the flow of the Hamiltonian vector field XHt of Ht. Let L be a Lagrangian submanifold, invariant under some antisymplectic involution of M. Assume that L and φH (L) intersect transversally. Then the number of intersection points of L and φH (L) can be estimated from below by the sum of the Z2 Betti numbers of L, i.e.
Up to now,[when?] the Arnold–Givental conjecture could only be proven under some additional assumptions.
