%0 Journal Article %T Adjoints of composition operators with rational symbol %A Christopher Hammond %A Jennifer Moorhouse %A Marian E. Robbins %J Mathematics %D 2007 %I arXiv %R 10.1016/j.jmaa.2007.10.039 %X Building on techniques developed by Cowen and Gallardo-Guti\'{e}rrez, we find a concrete formula for the adjoint of a composition operator with rational symbol acting on the Hardy space $H^{2}$. We consider some specific examples, comparing our formula with several results that were previously known. %U http://arxiv.org/abs/0705.0488v1
