left-aligned equationsWhy are equations left-aligned?
The left justification of the equations is not random but part of the LIPIcs style and the other styles of Dagstuhl Publishing. We decided some years ago that we prefer text-like content (incl. equations and captions) to be left-justified and not centered. In contrast, figures and tables are centered. See also the LIPIcs Author Guidelines:
The alignment of the equations is thus a deliberate style decision of the series. Therefore, we cannot comply with any request for centering.
