Displayed equations should be centralized and numbered
consecutively, with the equation number flush right
(i.e. right-justified) and enclosed in parentheses. Equations
should be referred to in the text as Eq. (X), where X is the
equation number. In multiple-line equations, the number should
be given on the last line. Please ensure that equations are
numbered correctly, without repetition, and that no important
equations are omitted from the numbering scheme.
Equations should be set in the same font size as the main text,
with superscripts and subscripts 2-3 points smaller.
