In sequent calculus, what's going on with sequents with multiple formulae in the succedent? The sequent proof systems I learned only allowed one formula on the right hand side of the sequent, and $\phi_1, \ldots, \phi...
of formulas, called a _sequent_. A sequent is _valid_ it it satisfied in every interpretation.

Finally, sequent calculus generalizes the form of a natural deduction judgment to
a syntactic object called a sequent. Origin of word "sequent"
The word "sequent" is taken from the word "Sequenz" in Gentzen's 1934 paper.

In natural deduction, may a sequent we want to prove have another sequent as its premise? For example can we have something like $(A\vdash B)\vdash C$ to prove in natural deduction? I've seen a single sequent this sha...
Usually not. $\vdash$ expects a list (or set) of (object-level) propositions and a proposition and $(A\vdash B)$ is not a(n object-level) proposition. That is, it's not a formula of the object language. This is almost always the case. There are systems of nested sequents (e.g.) that do allow things ...

Need to find a proof for the sequent p→(q ∨ r), ((¬p)∨(¬q)) ⊢ ¬r I started a book on logic in computer science I went over the rules of propositional logic but I can't seem to be able to prove this sequent. Can anyon...
The sequent is false. If you take $p$ False and $r$ True then both antecedents are true but the succedent is False.

Encoding Transition Systems in Sequent Calculus_文档下载
Intuitionistic and linear logics can be used to specify the operational semantics of transition systems in various ways. We consider here two encodings: one uses linear logic and maps states of the transition system into formulas, and the other uses intuit

Prove implication sequent I need to prove the sequent $P \to Q \vdash \neg P \lor Q$ without using the law of the excluded middle $(P \lor \neg P)$ or $( Q \lor \neg Q)$.
Here is a proof done in Fitch: ![enter image description here](
