<div><br>
</div>
<div>Abstract: <span style="background-color:rgb(255,255,255)">The study of outer automorphism group of a free group Out(F</span><span style="background-color:rgb(255,255,255)">) is closely related to study of Mapping Class
Groups. The Out(F</span><span style="background-color:rgb(255,255,255)">)
analog of a pseudo-Anosov homeomorphism is called a fully irreducible.
We will talk about types of fully irreducible elements, geometric and
hyperbolic, and prove that they</span><span style="background-color:rgb(255,255,255)"> act
on the space of geodesic currents with north-south dynamics. As an application, we will give a criterion for subgroups of Out(F</span><span style="background-color:rgb(255,255,255)">) to contain a hyperbolic fully irreducible element using ping-pong
type arguments. <br><br></span><br><div style="font-size:12.8px"><span style="font-size:12.8px">Place : 106, Bomonti campus, MSGSU</span></div><div style="font-size:12.8px"><span style="font-size:12.8px">Time : 16:00, Thursday, May 7<br><br></span></div><div style="font-size:12.8px"><span style="font-size:12.8px">Best,<br></span></div><div style="font-size:12.8px"><span style="font-size:12.8px">Mohan Ravichandran<br></span></div></div></div>
