Fredholm Theory for Pseudoholomorphic Curves with Brake Symmetry
Beijia Zhou, Chaofeng Zhu
In this paper we study pseudoholomorphic curves with brake symmetry in symplectization of a closed contact manifold. We introduce the pseudoholomorphic curve with brake symmetry an…

The Hörmander index in the finite-dimensional case
Yuting Zhou, Li Wu, Chaofeng Zhu
In this paper, we calculate Hörmander index in the finite-dimensional case. Then we use the result to give some iteration inequalities, and prove almost existence of mean indices f…

The Maslov index in symplectic Banach spaces
Bernhelm Booss-Bavnbek, Chaofeng Zhu
We consider a curve of Fredholm pairs of Lagrangian subspaces in a fixed Banach space with continuously varying (weak) symplectic structures. Assuming vanishing index, we obtain in…
