My confusion about ##u## and ##\mu##

Message
[QUOTE="fresh_42, post: 6451253, member: 572553"] ##u## and ##\mu## are two very different letters, not only because one is Latin and the other one is Greek, but also because ##\mu ## is the Greek ##m##. I cannot find any ##\mu## in your photo above, and I think it is more a case of sloppy handwriting than it is a case of interchanging the two. However, there are some conventions: ##u## is normally a function, ##\mu## is either an index or a measure. This means that ##\int u\,d\mu## makes sense. But as with all conventions, this is no rule and everybody can use it in a different way. [/QUOTE]
