Hall of Ideas G

Dejan Stojkovic (SUNY at Buffalo)

2:00 PM → 2:18 PM Four-dimensional General Relativity from higher-dimensional Gauss-Bonnet gravity

Speaker: Ingunn Kathrine Wehus (University of Oslo & Caltech)

Slides wehus.ppt

2:20 PM → 2:38 PM KK Gravitons and Dark Matter

Speaker: Nausheen Shah (University of Chicago)

2:40 PM → 2:58 PM A Modest Appeal to Conformal Gravity

Speaker: Manu Paranjape (UniversitÈ de MontrÈal)

We review the ideas behind conformal gravity viewed as an alternative theory of gravitation, and how it presents a solution to the missing matter problem. We then focus on our own work involving the deflection of light and on the existence of spontaneous breaking of conformal invariance via classical solitonic solutions.
