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.
