Linear logic algebras

Abbreviation: LLA


A linear logic algebra is a structure $\mathbf{A}=\langle A,\vee,\bot,\wedge,\top,\cdot,1,+,0,\neg\rangle$ of type $\langle 2,0,2,0,2,0,2,0,1\rangle$ such that

$\langle A,\vee,\wedge,\cdot,1,\neg\rangle$ is an involutive residuated lattice

$\bot$ is the least element: $\bot\le x$

$\top$ is the greatest element: $x\le \top$

$+$ is the dual of $\cdot$: $x+y=\neg(\neg x\cdot\neg y)$

$0$ is the dual of $1$: $0=\neg 1$

It is not unusual to give several (equivalent) definitions. Ideally, one of the definitions would give an irredundant axiomatization that does not refer to other classes.


Let $\mathbf{A}$ and $\mathbf{B}$ be … . A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a homomorphism: $h(x ... y)=h(x) ... h(y)$


An is a structure $\mathbf{A}=\langle A,...\rangle$ of type $\langle ...\rangle$ such that

$...$ is …: $axiom$

$...$ is …: $axiom$
