Limit theory under sub-linear expectation is challenging and has attracted a great deal of attention and exploration. Adopt the different approach than probability space, under the condition that Choquet integrals existed, we used Hölder inequality and extended negatively dependent (END) capacities inequality to study the complete integral convergence for randomly weighted END random variables sequence under the sub-linear expectation, and obtained the theorems of complete convergence and complete integral convergence, thereby extending the corresponding results from the probability space to the sub-linear expectations space. Moreover, the results extend some corresponding ones under sub-linear expectations.
