| Description: | [DPS Seminar] Biswajit Paul (S. N. Bose National Centre For Basic Sciences, Kolkata) -- Gauge Symmetries In higher derivative theories |
| Date: | Wednesday, Feb 19, 2014 |
| Time: | 2 p.m. - 3:30 p.m. |
| Venue: | LH 1, JC Bose |
| Details: | Since their introduction, theories with higher derivatives are unavoidable and frequently arise in different contexts. Hamiltonian formulation for Higher derivative theories become necessary and is discussed in the first order formalism. This Hamiltonian formulation is applied to the minisuperspace cosmology following from the geodetic brane gravity model introduced by Regge and Teitelboim. The analysis is done using the equivalent first order approach. The constraint algebra is shown to realize a truncated Virasoro algebra. The gauge generator containing the exact number of gauge parameters is constructed. Equivalence between the gauge and reparametrization symmetries has been demonstrated. Complete gauge fixed computations have been provided and formal quantization is indicated. |
