User talk:Lord Farin/Backup/Definition:Formal Language/Primitive Symbol

Somehow I feel that the primitive symbols need to be the variables and constants of the language, but as currently stated it seems to encompass even the parentheses used to well-define the formulae; this is not very useful when applied to top-down formal grammar atm. --Lord_Farin 16:23, 14 June 2012 (EDT)


 * That's the definitions we're running with, as that's the definitions used in the works I consulted to get this section off the ground. There is another definition for variables and constants, it might be something like "terms" or something.


 * Everybody has their own ideas as to how these pages should be structured, and they're all more or less right. I don't know what the answer is apart from put every single variant down in "also known as" and "also defined as" sections. I confess that the muddle and confusion and complete lack of any sort of consistency throughout the literature cause me to throw the whole bloody subject across the room in frustration. --prime mover 16:29, 14 June 2012 (EDT)


 * While I can definitely recognise myself in that last statement; I gratefully thank GFP for finding (at least, at first sight) the page I was looking for and linking to it. --Lord_Farin 17:18, 14 June 2012 (EDT)


 * To enhance my understanding of what is being defined here, would you please answer the following questions:


 * Is the primary purpose of the signs to provide handles for the formal grammar to attach to (like parentheses)? If not, what is the purpose and extent?
 * In PropLog, is $\land$ a sign or a letter? More generally, what are letters and signs in PropLog?
 * What books are/were your ref. for these pages? I'd like to try and grasp the author's perspective directly
 * TIA. --Lord_Farin 17:44, 14 June 2012 (EDT)


 * mainly, and it should all be there under the PropLog category. I was inexperienced with MediaWiki capabilities at the time, so it's a bit messy. Start here: Category:Propositional Calculus and see what you can make of it. --prime mover 17:59, 14 June 2012 (EDT)


 * Thanks; fortunately there is an ebook version available so that I can start right away. Well, that is, after I get some sleep. --Lord_Farin 18:16, 14 June 2012 (EDT)
