I have a very long series of equations that I want to align and emphasize by boxing them. I've used empheq with success before, but never ran into the problem of having my equations over flowing to another page. Is there a way to have the box terminate at the bottom of the page and continue on the other page while retaining the equation alignment?

    I'm afraid this is not possible for individual boxes. What you can do is to put the whole series of equations in a framed environment, which will break across pages.

    It is stated in the empheq manual that the empheq blocks cannot be broken.

    @daleif - I think you should convert your comment to an answer. :-)

One of the side-effects of using empheq us that the math construction cannot be broken across pages and \intertext is not supported.

The reason is that empheq is actually using aligned and friends internally, and these have this limitation. Empheq adds custom eq numbering to these inner constructions.

  • @nonameswereavailable not that I know of, unless tcolorbox has some tricks up its sleeve
