What does a ellipsis directly following a summation mean?

  1. Oct 23, 2012 #1
    I've never seen this notation before. What does the ellipsis right after the first summation mean:
    [tex]\begin{equation}
    \label{aixi_eq}
    a_t^* = \arg\max\limits_{a_t}\sum\limits_{o_t r_t} \dots \max\limits_{a_{t+m}}\sum\limits_{o_{t+m} r_{t+m}}[r_t + \dots + r_{t+m}]
    \sum\limits_{q:U(q,a_1...a_{t+m})=o_1 r_1 ... o_{t+m}r_{t+m}}2^{-\ell(q)}.
    \end{equation}[/tex]

    My guess: a string of summations with at+k with 0<k<m.

    That's it, thanks.
