Boldmath Lucida

Boldmath Lucida

[Sytse Knypstra]

Hi all,

When writing a mathematical text I encountered a few problems with bold 
symbols.
Under the line you will find three problems (dutch interface).
Are they due to my insufficient knowledge of installing fonts?
Thanks for any comment.

Problem 1:

${\bfmath x}$   gives boldface standard  x.

${\bfmath x}{\bfm }$  gives boldface italic $x$ which is what I want.

${\bfmath \Gamma}$  gives a space;

only ${\bfmath \Gamma}{\bfm }$  gives the boldface italic $\Gamma$ that I want.


Problem 2:

${{\bfm \beta}}$  gives a wrong glyph (in fact the ligature 'fi').


Problem 3:

After $\bfm \beta$ the text is no longer  printed in the same Lucida Bright 
style as before.
