Floer homology of certain pseudo-Anosov maps

Floer cohomology is computed for the elements of the mapping class group of a surface $\Sigma$ of genus $g \gt 1$ which are compositions of positive and negative Dehn twists along loops in $\Sigma$ forming a tree-pattern. The computations cover a certain class of pseudo-Anosov maps.
