=====Right quasigroups=====

Abbreviation: **RQgrp**
====Definition====
A \emph{right quasigroup} is a structure $\mathbf{A}=\langle A,\cdot,/\rangle$ of type $\langle 2,2\rangle $ such that

$(y/x)x = y$

$(xy)/y = x$

Remark: 

==Morphisms==
Let $\mathbf{A}$ and $\mathbf{B}$ be right quasigroups. A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a homomorphism: 

$h(xy)=h(x)h(y)$, $h(x/y)=h(x)/h(y)$.
