IISc physicists find a new way to represent 'pi'

• ano-ther 2y ago
  The new representation is at the very end of their paper: https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.132.221601 https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.132.221... How does the n-1 subscript on the second parentheses work?

    It's the Pochhammer symbol as defined on page 2 of the PDF. https://en.wikipedia.org/wiki/Falling_and_rising_factorials https://en.wikipedia.org/wiki/Falling_and_rising_factorials
