## Bounded residuated lattices

Abbreviation: RLat$_b$

### Definition

A bounded residuated lattice is a residuated lattice that is bounded:

$\bot$ is the least element: $\bot\vee x=x$

$\top$ is the greatest element: $\top\vee x=\top$

##### Morphisms

Let $\mathbf{A}$ and $\mathbf{B}$ be bounded residuated lattices. A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a residuated lattice homomorphism $h:A\rightarrow B$ that preserves the bounds: $h(\bot)=\bot$ and $h(\top)=\top$.
