The Ruelle dynamical zeta function is a p roperty of flows on compact manifolds\, which encodes information on perio dic flow curves. Interestingly\, the absolute value of this function at ze ro is often equal to the analytic torsion of the manifold\, even though th e latter does not involve the flow at all. Fried’s conjecture is the pro blem to determine when this equality holds. With Saratchandran\, we constr ucted equivariant versions of analytic torsion and the Ruelle zeta functio n for proper group actions\, and posed the question when an equivariant ve rsion of Fried’s conjecture holds. With Pirie\, we are investigating thi s conjecture for a specific type of flows: suspension flows of diffeomorph isms.\n LOCATION:https://researchseminars.org/talk/NYC-NCG/160/ END:VEVENT END:VCALENDAR
