On the exact regions determined by Kendall's tau and other concordance measures
Abstract We determine the upper and lower bound for possible values of Kendall's tau of a bivariate copula given that the value of its Spearman's footrule or Gini's gamma is known, and show that these bounds are always attained. Mathematics Subject Classification (2020). 62H20, 62H05, 60E05.
