=====Generalized separation algebras=====

Abbreviation: **GSepAlg**

====Definition====
A \emph{generalized separation algebra} is a [[cancellative partial monoid]] such that 

$\cdot$ is \emph{conjugative}: $\exists w, \ x\cdot w=y \iff \exists w, \ w\cdot x=y$.

==Morphisms==
Let $\mathbf{A}$ and $\mathbf{B}$ be cancellative partial monoids. A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a homomorphism: 
$h(e)=e$ and
if $x\cdot y\ne *$ then $h(x \cdot y)=h(x) \cdot h(y)$.
