Space Above Equations

Question

Vertical spacing before and after equation environment: empty line or not?

I am using iPython Notebooks and a utility called nbconvert to translate notebooks into LaTeX. One problem is generated equations have too much space on top; I tried to play with \baselineskip parameter without much success. Any ideas on how to fix this? I am attaching the generated code; I am looking for additive fixes, parameter settings using the packages present in the tex file - I do not have much control on the main part of the nbconvert tool, I prefer improving the existing usage scenario.

% TODO: unfortunately, it seems that using a framed codecell environment breaks
% the ability of the frames inside of it to be broken across pages.  This
% causes at least the problem of having lots of empty space at the bottom of
% pages as new frames are moved to the next page, and if a single frame is too
% long to fit on a page, will completely stop latex from compiling the
% document.  So unless we figure out a solution to this, we'll have to instead
% leave the codecell env. as empty.  I'm keeping the original codecell
% definition here (a thin vertical bar) for reference, in case we find a
% solution to the page break issue.
