Abstract:

Moufang’s theorem states that if $Q$ is a Moufang loop with elements $x$, $y$ and $z$ such that $x\cdot yz = xy \cdot z$, then these three elements generate a subgroup of $Q$. The paper contains a new proof of this theorem that is shorter and more transparent than the standardly used proof of Bruck.
