Text Formatting ⇒ Automatic hyphenation for words with special characters

[bircoph]

Hello,

I'm wondering is there any way to automatically hyphenate words with special chars? Especially I'm interesting in the words containing '-' themself, like "$\Delta$-resonanse", or
$\Sigma$-hyperon.

Of course, I can manually set hyphens for those words (using '\-'), but this is annoying. Even new commands doesn't help much: I have dozens of this words with different endings (in Russian you have 6 possible cases for the word, not only 2 as in English).

I found a solution: you can use ["=] instead of [-] and words with dash are hyphenated automatically. Though, it works only if babel with russian language is set.
