Notation for a list

  1. May 29, 2013 #1
    Greetings,

    Is there a commonly accepted notation for a list in mathematics, of an identical form to Ʃ for a summation? If so, what is the name of the symbol (that would be used in place of L, below), and how would it be typed in LaTeX?

    For instance, it might look something like,

    [itex]L^{1}_{n}[/itex]Ai[itex]\equiv[/itex]A1,A2,...,An,

    except that the 1 and the n on the LHS would be directly below and above the L, as they would be with Ʃ for a summation.

    Obviously, this is not a critical issue, but I often run into situations where that notation would be convenient and cleaner than writing a full list or ...'s all of the time...

    Thanks for any help you can give.

    ##\{A_i\}_{i=1}^n##

    or ##\{A_i\}_{i\in I}## for some index set I (provided I is defined)

    or just "##A_i## for ##i = 1, \ldots, n##"
