Is the half iterate of 2sinh(x) analytic near R ? - tommy1729 - 03/07/2013 Is the half iterate of 2sinh(x) - expanded from fixpoint 0 - analytic near R ? And does it satisfy its functional equation ( composition towards 2sinh(x) ) wherever it is analytic ( near R ) ? I know the taylor series is messed up because we have 2 complex conjugate fixpoints. However a taylor series can converge outside its radius. This might be a general idea that we need a general tool for. regards tommy1729 RE: Is the half iterate of 2sinh(x) analytic near R ? - tommy1729 - 03/13/2013 Does the taylor series expanded from 0 converge outside its radius ? |
