The following MCE points out that DeclareMathOperator, if its second argument (name text) contains periods, adds spaces after those periods:

endalign*
enddocument


enter image description here



Do you know why and how to get rid of these spaces?

  • DeclareMathOperatorlimonel.i.m. Note that while the l.i.m. will still line up with your text case, there will be a gap following the last ., because l.i.m. is now an operator, whereas textl.i.m. is a math atom.

  • Using . ? Untested, it just makes the dot an ord. Which math operator is that? Never seen one with punctuation in it before

  • @daleif . works nicely indeed. Concerning the operator, some authors use it for denoting the convergence in the mean square sense. I agree it is quite strange :)

It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code.

Confectionery

Image
Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
