摘要： We establish self-duality of the resolvent average defined on the symmetric cone of a $JB$-algebra. It induces the monotonicity of the resolvent average and the geometric mean of arithmetic and harmonic means for parameters. Nonexpansive property of these means for the Thompson metric on the cone and its applications to nonlinear equations are given.
