11. Roth sold the film rights to " The Divergent Series " to Summit Entertainment. 12. The most general method for summing a divergent series is non-constructive, and concerns Banach limits. 13. Most but not all summation methods for divergent series extend these methods to a larger class of sequences. 14. There are several different summation methods called zeta function regularization for defining the sum of a possibly divergent series 15. He briefly reprised the role in " The Divergent Series : Allegiant " ( 2016 ). 16. A way to assign a value to the divergent series is by using Borel summation, where one formally writes 17. In mathematics, a "'divergent series "'is an infinite series that is not limit. 18. You would probably like the book ( or other books with Tauberian theorems or Divergent series in the title ). 19. Taking regularity, linearity and stability as axioms, it is possible to sum many divergent series by elementary algebraic manipulations. 20. In mathematics, "'Borel summation "'is a summation method for divergent series , introduced by.
