almost periodic function

  • 准周期函数：准周期函数是一类有近似于周期性质的函数，是连续周期函数的推广。概周期函数尽管未必有严格的周期性，但可拥有一些比周期函数更好的性质。

Almost periodic function

  • abstract: In mathematics, an almost periodic function is, loosely speaking, a function of a real number that is periodic to within any desired level of accuracy, given suitably long, well-distributed "almost-periods". The concept was first studied by Harald Bohr and later generalized by Vyacheslav Stepanov, Hermann Weyl and Abram Samoilovitch Besicovitch, amongst others.
