Hello,

Wrap the letter with \mathbb{}

Note that this works with capital letters only :

For the 1, I bet you want to use it for the indicator function... I don't think there is a simple command with it. But use \bold{1} (bolded) and we'll understand you :D

http://www.statslab.cam.ac.uk/~elie/ext/tex/ look "Example Code with Overlaps". But I cannot open the file due to problems of mine. - March 20th 2009, 02:57 PMReckoner
