A Lagrangian sphere which is not a vanishing cycle
François Greer
We give examples of Calabi-Yau threefolds containing Lagrangian spheres which are not vanishing cycles of nodal degenerations, answering a question of Donaldson in the negative.

Monotone Lagrangian Floer theory in smooth divisor complements: II
Aliakbar Daemi, Kenji Fukaya
In the first part of the present series of papers, we studied the moduli spaces of holomorphic discs and strips into an open symplectic manifold, isomorphic to the complement of a…

Monotone Lagrangian Floer theory in smooth divisor complements: I
Aliakbar Daemi, Kenji Fukaya
In this paper, Floer homology for Lagrangian submanifolds in an open symplectic manifold given as the complement of a smooth divisor is discussed. The main new feature of this cons…
