Could it be a script F?

There is no e in yours and it looks like yours is bolded

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...

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...)

None of them are working
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]

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?

I'm not aware of any convention for the typography to represent a field.
This means you can use any typeface you want.
Most common seems to be simply italic F ([itex]F[/itex]).

Also, there's no distinction in typography for an ordered field.

The notation [itex]\mathbb{F}[/itex] is used sometimes for field. But mostly for finite field. So the field with 9 elements is often written as [itex]\mathbb{F}_9[/itex].

If we are working with arbitrary fields, then it seems that F, K and L are the most common notations for fields. With F standing for field, K standing for Korper (german) and L standing for Lichaam :biggrin:

Ah finally someone who knows it by a name that I'm familiar with. :approve:
Won't this make you eligible for you-know-what?
Also, it gives your statement that you're living in a field a new meaning! :biggrin:

There was once a PhD defense in my university. The title was "special places on fields", but then in dutch. The auditorium was packed until they realized that it was about mathematics.
