Convert pdf with math formulas to epub

I have used Calibre to convert pdf-files containing mathematical formulas to epub and the results looks like this:

f

w

and therefore:

2

L

D  c S q 

(4.9)

f

w

2

(pdftoepub delivers the same result)

Hardly satisfactory.
Is there any way to improve on this?
Thanks in advance for any tip.

Do you have something like a TeX source for the PDFs? If so, use that to convert to ePub and not PDF through something like pandoc.

If no, what do you get just copying and pasting the equation from the PDF? The same garbage? Or at least something a bit closer? I don't think there's much you can do that's not going to require a bunch of manual tweaks and fixes.

Thanks,
my problem is that my source is a 780 pages pdf file with at least one equation on each page and that the author is deceased.

PDF is for viewing and Printing. Only image scans are worse to convert.
