Web31 Mar 2016 · If this is not desired, use nosumlimits (valid for \sum, \prod, \coprod, \bigoplus and \bigotimes etc operators, but not for integrals) The 'correct' usage should follow the guideline that limits above and below should be used only in purely mathematical context, not inline with other text, since the line height is stretched here. Webconsider the sum S = ∑n i=k a i and make the substitution j =i−k, we have that i =k +j so that the term a i in the summation has to be replaced by a k+j, that is S = ∑ a k+j. In order to determine the limits in the summation above, we observe that for i =k we get j =k −k =0 while for i =n we have j =n−k. Therefore, S = ∑n−k j=0 a ...
