In this contribution we stress the importance of Sklar's theorem and present a proof of this result that is based on the compactness of the class of copulas (proved via elementary arguments) and the use of mollifiers. More details about the procedure can be read in a recent paper by the...

反证法假设有最大质数m那么将m之前所有的指数相乘并加1，所得的数与这些相乘的数都互质，即是质数，且比m大，矛盾所以不存在最大质数
In summary, the conversation discusses how to prove a rule for differentiable curves in $\mathbb{R}^3$ involving cross products. Two different proofs are given and it is determined that to use the product rule, the cross product must be written as a determinant. The correctness of one of ...
