We compute the product and coproduct structures on the fixed point Floerhomology of iterations on the single Dehn twist, subject to some mildtopological restrictions. We show that the resulting product and coproductstructures are determined by the product and coproduct on Morse homology of thecomplement of the twist region, together with certain sectors of product andcoproduct structures on the symplectic homology of $T^*S^1$. The computation isdone via a direct enumeration of $J-$holomorphic sections: we use a localenergy inequality to show that some of the putative holomorphic sections do notexist, and we use a gluing construction plus some Morse-Bott theory toconstruct the sections we could not rule out.
