Abstract
<p><span style="font-size: x-small;"><span style="font-size: 10pt;">The eponymous result is due to Bridson and Vogtmann, and was proven in their paper "Automorphisms of Automorphism Groups of Free Groups" (Journal of Algebra 229). While I'll remind you all the basic definitions, it would be very helpful to be already somewhat familiar with the outer space. </span></span></p>
