摘要
Let X and Y be positive weakly negatively dependent(WND)random variables with finite expectations and continuous distribution functions F and G with heavy tails, respectively. The asymptotic behavior of the tail of distribution of XY is studied and some closure properties under some suitable conditions on ˉ F(x)= 1 F(x)and ˉ G(x)= 1 G(x)are provided. Moreover, subexponentiality of XY when X and Y are WND random variables is derived.
