i dont really know what defines metamath
 one year ago

ParthKohliBest ResponseYou've already chosen the best response.0
It comes under Pure Mathematics. @estudier is telling you to ask them in the Metamath group.

ParthKohliBest ResponseYou've already chosen the best response.0
Mathematical logic per se is a study which comes under Pure Mathematics.

estudierBest ResponseYou've already chosen the best response.0
Roughly speaking it is the use of math to talk about math.

what ever you reckon
 one year ago

ParthKohliBest ResponseYou've already chosen the best response.0
Because they have no mathematical logic group, metamath is the best group to ask in. In fact, Metamath is an appropriate description of mathematical logic, because it's mathematics about mathematics.

To be honest, I am not so sure that we really need this section in OS. At least, I think that there would not be so many members of that group.

but logic about logic is maths

Yeah... it's sort of a conclave thing.

One thing I noticed missing is a Miscellaneous/Other category or a category for Recreational Mathematics

estudierBest ResponseYou've already chosen the best response.0
Anyway, that is not the question here, sorry...

estudierBest ResponseYou've already chosen the best response.0
I think it is a good idea to ask the question in the metamath group "What is metamath?" (And pin the thread, except u can't do that)
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.0
well so far i have some reason to post logic questions in the subtopic metamath, however i can think of equally valid reasons to post logic question in other subtopics, so i still am not convinced that metamath is the best section to post in
 one year ago

estudierBest ResponseYou've already chosen the best response.0
Where would you post it instead? Algebra? (I don't disagree with u, metamath only includes mathematical logic usually)
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.0
probability, statistics, discrete math

estudierBest ResponseYou've already chosen the best response.0
Exactly which sort of logic are we talking about?

where do you think is best for this question \[(1,2)\cap[2,3)=\]
 one year ago

estudierBest ResponseYou've already chosen the best response.0
Set Theory = Metamath Applications of Set theory = The area in which it is being applied.
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.0
im talking about these operators \(\neg,\land,\lor,\Rightarrow,\Leftrightarrow,\exists,\forall,\)
 one year ago

estudierBest ResponseYou've already chosen the best response.0
Again, you have to distinguish between the theory and the applications
 one year ago

estudierBest ResponseYou've already chosen the best response.0
The theory is that of formal systems (First order logic and in general, nth order logics).
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.0
well im doing a course you see, and we have covered all the above operators , then some stuff on proof, ( like proof of \(\sqrt{2}\not\in\mathbb Q\}\) and now we are starting some set theory

Yes, these are all connected...

i feel there should be a single subtopic that can accommodate all these, maybe it is just maths
 one year ago

estudierBest ResponseYou've already chosen the best response.0
propositional logic  simple declarative propositions, firstorder logic  covers predicates and quantification as well
 one year ago

estudierBest ResponseYou've already chosen the best response.0
These are then used in ZFC (a formal mathematical system) to prove things using the language of sets
 one year ago

estudierBest ResponseYou've already chosen the best response.0
At a very abstract level, I would call this metamath. Otherwise, it would depend on where it was being applied.
 one year ago

estudierBest ResponseYou've already chosen the best response.0
However it does seem to be to be very algebraic in nature.
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.0
my main reason for disliking metamath as the best option, is that the OS group dosent have much history of use of these symbols
 one year ago

estudierBest ResponseYou've already chosen the best response.0
Basically, I agree, we could get along fine without this subgroup and instead maybe have one called "Proofs, Logic and Sets" or something like that.

logic is under discrete mathematics......
 one year ago

estudierBest ResponseYou've already chosen the best response.0
I have seen people say that logic (and set theory/proofs) is a part of discrete math but I fail to see why that should be, logic, proof and set theory is applied across all of mathematics.
 one year ago

lgbasalloteBest ResponseYou've already chosen the best response.0
if you consider logic to be under mathematics, then it's under discrete mathematics. Otherwise, you might as well consider logic to be under philosophy
 one year ago

estudierBest ResponseYou've already chosen the best response.0
If it is the theory of mathematical logic then it is definitely metamathematics, the applications could be anywhere but to me the usage seems most like algebra (symbolic manipulation according to some rules). There are a lot of things under the heading "logic", it depends what u mean and whether you are talking about applications or theory.

shadowfiendBest ResponseYou've already chosen the best response.1
That's a good question. Keep in mind that if you can't find a valid subtopic, you can absolutely just post it directly in math. That said, you're right that set theory and formal logic could probably use some sort of subtopic. I feel like lumping proofs in there is random and unnecessary, however (despite the fact that proofs often rely on formal logic). Perhaps a logic & sets topic? The correlation there is stronger, I feel.

Well Discrete math is basically compromised of Logic, Set Theory, Relations, Cardinality, Functions such as mapping a function onto or one to one and sometimes graph theory. So I guess you would ask a logic question in the Discrete math section.
