Legendrian变形下的辛能量与Lagrange交

Symplectic Energy and Lagrangian Intersection Under Legendrian Deformations

Hai-Long Her

摘要:

设M是紧致辛流形,L是闭的拉格朗日子流形,且L在M的接触化中可提升为勒让德子流形.对L的任意勒让德变形满足一定条件,得到一个新的拉格朗日子流形L '.证明了L和L'的交数可以由L的$Z_2$ -贝蒂数之和估计,只要它们是横交的.

英文摘要:

Let M be a compact symplectic manifold, and L be a closed Lagrangian submanifold which can be lifted to a Legendrian submanifold in the contactization of M. For any Legendrian deformation of L satisfying some given conditions, we get a new Lagrangian submanifold L'. We prove that the number of intersection of L and L' can be estimated from below by the sum of $Z_2$-Betti numbers of L, provided they intersect transversally.
