I am curious if there is a "correct" way whether to add a space before/after the align:

Thus
(Should there be a space here?)    
\begin{align*}
\end{align*}
(Should there be a space here?)  
Since $\epsilon>0$ is arbitrary...

There is a clear difference between the two (in terms of spacing) and sometimes if I don't add a space after "\end{align*} there is a strange distortion.

Thanks for expert help.

  • Could you post a minimal example demonstrating what you're after?

    If by "space" you mean empty line in the code, then no, you don't generally want that. More specifically it depends on whether the set of equations is at the end of a paragraph (in which case you want a paragraph break - empty line - after it) or inside a paragraph (in which case you don't want paragraph breaks anywhere).

You should never have a blank line before a display: TeX produces a spurious white line (a blank paragraph, not vertical space) in that case.

You need a blank line after the display if the following text is a new paragraph and don't need a blank line if it is not.

  • A blank line before a display will allow a page break, which is almost always a bad idea.
