    Could it be a script F?

    I thought that perhaps the e might actually be the kind of loop you see on my F.

    Sorry that it is bolded. :blushing: It was just the first F I could find that had such a loop.


    As an alternative it might be a H...

    OKay but what is it called?
     
  7. Oct 25, 2011 #6
    H, pronounced "aych":biggrin:
    In what context does it appear? Preferably, post the expression.

    I tried [tex]\aych[/tex]

    Nothing

    It appears in Ordered Field

    Since it is supposed to represent an (ordered) field, I think F, pronounced "ef", which is the first letter of "field".

    [tex]\ef[/tex]

    [tex]\ofield[/tex]

    None of them are working

    Unless it is an H, in which case mayhaps it refers to the quaternions? (it would be a strange font, though...)

    It's just a stylized letter, it can mean whatever you want. It isn't going to be under "/field" or anything like that.

    It seems you're trying Latex?

    That would be:
    [tex]\mathscr F[/tex]
    or
    [tex]\mathcal F[/tex]

    it kinda looks like it, but is it correct to use it?

    Hmm, this may seem a bit repetitive, but I have to ask... use it when and where? :confused:

    Oh, and as for the name, perhaps the Unicode name "SCRIPT CAPITAL F" (code U02131) covers it?

    for ordered fields.

    Yes, you can use script capital F for an ordered field.

    what about [tex]\mathbb{F}[/tex]? is that just for normal fields and not ordered ones?
