摘要
利用指数发生函数证明组合数学中的错排问题,并利用错排数的指数发生函数得出一组有关错排数问题的新的恒等式.
Wrong Permutation Problem in combination mathematics was proved by using the exponential generating function. Using the exponential generating function of Wrong Permutation Number, we can get a new identity concerning Wrong Permutation Number.
