摘要：Let (X,ω) be an exact symplectic manifold (with contact-type boundary). Choose an almost complex structure J compatible with ω. Physicists associate a Landau-Ginzburg model for a given superpotential W : X → C with the structure of symplectic Lefschetz fibration. For any two non-degenerate critical points x and y of W and a specific phase ζ, one can obtain the ζ-solitons and the associated ζ-instanton equation. To study the moduli space of solutions of ζ-instanton equation, it is important to define a Maslov-type index for ζ-solitons. In this talk, we will discuss the definition of such index.
