/ Abstract
We give an explicit description of the Floer cohomology of a family of Dehn twists about disjoint Lagrangian spheres in a w+ - monotone rational symplectic manifold. As a byproduct of our framework, in a monotone symplectic manifold we are able to define a class in the fixed point Floer cohomology of a Dehn twist by counting half strips bound to the given Lagrangian sphere and prove it must vanish. In subsequent work we plan on using this vanishing result to give a new geometric proof of Seidel's long exact sequence.
