There is an error in one of the major results in our original paper ‘Equivalent weights and standard homomorphisms for convolution algebras on ℝ+’. We describe the error and give a counterexample to the result as stated. We then give a substitute result which is in many ways stronger than the erroneous result. We will also indicate what changes need to be made in the original paper to accommodate the replacement of the erroneous result by the substitute.
