What About Uncountable Theories?[edit]

This page is very nice, but probably ought to be rewritten in a more general way. The spectrum function I, is not only used for theories in countable languages, as is stated in the article. Much work has been done on the spectrum of complete theories (having infinite models) in general. For instance the Baldwin-Lachlan Theorem, among many others.

Stupid (possibly) suggestion.[edit]

Since "uppercase i" and "lowercase L" look identical in most sans-serif fonts, it's impossible for viewers to know if the expression "I(T, alpha)" means "uppercase i", "lowercase L", or potentially even "pipe" or "vertical stroke". It might be preferable if this could be rendered in a serif font. Is that practical?

I had to copy and paste into notepad to tell what symbol I was, for example (though in retrospect, I could have clicked "Edit" to see it in Times). I realize this is a problem in general and is not Wikipedia specific but it's something I expect most site readers and editors face. TricksterWolf (talk) 04:00, 19 March 2012 (UTC)
