How is Fredkin and Toffoli's Conservative Logic related to Linear Logic?
In the answers to this question, Timothy Gowers asks:
I've been interested in this question for some time. I haven't put any serious thought into it, so all I can offer is a further question rather ...

Is Girard's LU just an embedding of classical and intuitionistic logic into linear logic?
This question is about Girard's system LU, presented in his paper On the unity of logic. Girard starts by giving a "modal" sequent calculus with two zones of both hypotheses and consequents, $\Gamma;\...

Can linear logic be used to resolve unexpected hanging/surprise examination paradox?
In the Unexpected Hanging Paradox, the prisoner tries to narrow down their date of execution using seemingly sound logical reasoning. They instead arrive at a contradiction. When the paradox is ...

Dioperads vs polycategories
As defined by Gan, a dioperad consists of sets of operations $P(n,m)$ with "$n$ inputs and $m$ outputs", which can be composed by joining one output of one operation to one input of another, giving ...

Internal logic in topos theory, monoidal categories, and quantum mechanics
To obtain the internal logic of a topos (roughly speaking), we associate a type of free variable with an object, and a statement about such a variable with a subobject of that object. Intuitively, the ...

Models of intuitionistic linear logic that reflect the resource interpretation
I am interested in models of intuitionistic linear logic, that is, the logic that you get if you take classical linear logic and restrict the set of operators to $\otimes$, $1$, $\multimap$, $\times$, ...

Looking for papers and articles on the Tarskian Möglichkeit
Some background: Łukasiewicz many-valued logics were intended as modal logics, and Łukasiewicz gave an extensional definition of the modal operator: $\Diamond A =_{def} \neg A \to A$ (which he ...

Are exponentials in categorical models of linear logic harmful?
Categorical models for linear logic with $\otimes$, $1$, $\&$, $\top$, $\oplus$, $0$, and $\multimap$ are typically symmetric monoidal closed categories (for modeling $\otimes$, $1$, and $\...

Conservativity of multiplicative linear logic over intuitionistic multiplicative linear logic
It is well known that multiplicative linear logic (MLL) is conservative over intuitionistic multiplicative linear logic (IMLL). In other words, if an IMLL formula is provable in MLL then it is already ...

Proof of ¬(¬1 ⊗ ¬1) in tensorial logic
I believe I once had a proof of this proposition, but it's been lost to the mists of time and old hard drives, so who knows if it was correct, and try as I might I can't seem to reproduce it.

Equivalent formulation of linear logic with more axioms and less inference rules
We can formulate classical (sequent) logic with only the structural inference rules including cut, and a collection of axioms like $A, B \vdash A \wedge B$. This is equivalent to the usual sequent ...
