I would like to use the "
\mathcal symbols" from
txfonts, but otherwise use the standard symbols. Including the package
txfonts changes all fonts, which I would like to avoid. The command
uses all math symbols from
txfonts, but I think that they are too thick (and the quantors look ugly), especially compared to the usual text font computer modern. Probably
should work, where TX has to be replaced by the correct family name of txfonts. Which is the correct one? I've already tried some names, but so far none has worked.
