Abstract: | We extend an inequality (which involves the Dobrushin coefficient of ergodicity; see Cohen et al.(4)) to any linear bounded operator with domain and codomain L
1-spaces. We use the extended Dobrushin coefficient of ergodicity, that appears in the inequality, in order to obtain sufficient conditions for the uniform asymptotic stability of a positive contraction of an L
1-space. We conclude the paper by studying a class of strongly asymptotically stable positive contractions. |
