I wish to type the symbol of an ideal B.

See the link below (I cannot attach a picture since I am new here) http://kobotis.net/math/ec/ShortNotes/sn_GaloisExtensionOfLocalField.pdf

But it is different from what I will get from \mathfrak{B}. How should I type it?

Welcome to TeX.SX. A tip: If you indent lines by 4 spaces, then they're marked as a code sample. You can also highlight the code and click the "code" button ({}). Usually, we don't put a greeting or a "thank you" in our posts. While this might seem strange at first, it is not a sign of lack of politeness, but rather part of our trying to keep everything very concise. Upvoting is the preferred way here to say "thank you" to users who helped you. –  Claudio Fiandrino Jan 22 '13 at 10:40

Your symbol is not \mathfrak{B}. It's a \mathfrak{P}

Thank you very much! I have misunderstood it for a long time. –  user59211 Jan 22 '13 at 12:52

Yeah, speak about confusion in that font, especially between IJ, YN, SO etc., not mentioning the lowercase letters... –  tohecz Jan 22 '13 at 13:04
    
Thanks to egreg for the edit. –  Pouya Jan 22 '13 at 13:36

The symbol in the PDF is a P from Euler Fraktur (eufm10). Use it with \usepackage{eulervm}.

eulervm is not for Fraktur. –  egreg Jan 22 '13 at 11:48
    
@egreg Yes, it does set up the shape, but does not define a math alphabet, or \mathfrak. –  mafp Jan 22 '13 at 12:21
