the purpose of this study is to find the percentiles of fuzzy numbersand to demonstrate their applications, which include finding weightedmeans, dispersion indices, and the percentile intervals of fuzzy numbers. thecrisp approximations of fuzzy numbers introduced in this paper are new andinteresting for the comparison of fuzzy environments, such as a variety of economic,financial, and engineeri...

We consider the problem of estimating mean a random vector based on i.i.d. observations and adversarial contamination. introduce multivariate extension trimmed-mean estimator show its optimal performance under minimal conditions.
