It looks like an F, but it also has an e

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. 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?

6. Oct 25, 2011

Number Nine

H, pronounced "aych"
In what context does it appear? Preferably, post the expression.

7. Oct 25, 2011

flyingpig

I tried $$\aych$$

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".

9. Oct 25, 2011

$$\ef$$

$$\ofield$$

None of them are working

Number Nine

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.

appears....where?

12. Oct 25, 2011

Math, Ordered Field, it appears in

Number Nine

Quote the passage in which it appears.

It seems you're trying Latex?

That would be:
$$\mathscr F$$
or
$$\mathcal F$$

flyingpig

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

16. Oct 25, 2011

I like Serena

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

17. Oct 25, 2011

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

18. Oct 25, 2011

flyingpig

for ordered fields.

19. Oct 25, 2011

I like Serena

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

what about $$\mathbb{F}$$? is that just for normal fields and not ordered ones?
