The newtxmath package has 2 variants of the there exists symbol and the forall symbol. While using the newpxmath package i see that there is only one and it looks quite ugly.

Can anyone help me out in getting a better thereexist and forall symbol with the newpxmath package.

Thanks.enter image description here

  • Now? Is the package named newtxmath or newpxmath? – user31729 Jan 12 '17 at 19:54
  • @ChristianHupfer newpxmath has the problem. – crskhr Jan 12 '17 at 20:03
  • As an aside, i would like to ask this question: We can scale the 2 packages newtx and newpx by giving the command \usepackage[scaled=1.5]{newtxtext}. Can such scaling be done with the "mathptmx" package? – crskhr Jan 12 '17 at 20:04
  • From the documentation for newtx: As of version 1.5, the old txfonts versions of \forall, \exists and \nexists have been removed and the Alt versions substituted. Both \forall and \forallAlt generate ∀, and similarly with \exists and \nexists.” – egreg Jan 12 '17 at 22:25

Starting from version 1.5 of NewTX, released on 2016/08/12, there is no alternate version of the quantifiers:

As of version 1.5, the old txfonts versions of \forall, \exists and \nexists have been removed and the Alt versions substituted. Both \forall and \forallAlt generate ∀, and similarly with \exists and \nexists.

Indeed, the following document shows what's claimed in the documentation.

\documentclass{article}
\usepackage{newtxtext,newtxmath}
\begin{document}
\verb|\exists\forall|: $\exists\forall$

\verb|\existsAlt\forallAlt|: $\existsAlt\forallAlt$

\texttt{\meaning\exists-\meaning\existsAlt}

\texttt{\meaning\forall-\meaning\forallAlt}
\end{document}

If I compile the same with TeX Live 2015, I get

The same document with px instead of tx produces what follows:

With TeX Live 2015, \existsAlt and \forallAlt produce errors. Removing them

\documentclass{article}
\usepackage{newpxtext,newpxmath}
\begin{document}
\verb|\exists\forall|: $\exists\forall$
\end{document}

produces

As you see, the ugly versions have been replaced in the current version of newpxmath.

  • Dear Greg, i understand this, and i also updated my Tex Distribution to 2016. But i am not sure, if that update comes with the latest version of newtx. Hence i think i am still facing the problem where \existsAlt command is not recognized by newpxmath. Is there anyway by which i can make sure, my newtx package is at its latest version? – crskhr Jan 14 '17 at 2:19
  • @S.C. Just don't use the alt version, which used to be illegal with newpxmath anyhow. What's your TeX distribution? – egreg Jan 14 '17 at 9:54
  • LOG FILE : This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016/Debian) (preloaded format=pdflatex 2017.1.13) 14 JAN 2017 16:02 Now if i use "\exists" command it still appears very very bold faced as I pointed out in the question. – crskhr Jan 14 '17 at 10:33
  • @S.C. TeX Live/Debian always lags behind, unfortunately. Ensure it's fully updated with the package tools of your Linux box. – egreg Jan 14 '17 at 10:35
  • How do i ensure that? What is the other way of installing TeXLive other than TeXLive/Debian – crskhr Jan 14 '17 at 10:51
