Helvetica math fonts

["Martin Verweij" <m.d.verweij@et.tudelft.nl>]

Hello,

I am preparing a style-file for a poster format for our laboratory. For the
text I intend to employ the Postscript Helvetica (phv) fonts. For the math
fonts, somebody has provided me with a style file 'helvetica+m' (see below)
by Alan Jeffrey. In this file there is a reference to the Helvetica math
font 'phvcm'
and a Symbol font 'psycm'. However, at my ctan-site (ftp.dante.de) I cannot
find these fonts. Since our work involves a lot af mathematics, it is
important for us to have good math fonts. Would you please indicate where I
may find the indicated fonts or what alternatives to these sans serif math
fonts exist ?

Regards,

Martin Verweij.
