The effective Lagrangian and vacuum energy-momentum tensor ( T"") due to a scalar field in a de Sitter- space background are calculated using the dimensional-regularization method. For generality the scalar field equation is chosen in the form ( '+ $R + m ')p = 0. If $ = 1/6 and m = 0, the renormali
