| 14:00 - 15:00 Weekly Seminar HEPCo Group Gravitational breathing memory and dual symmetries School PHYSICS Abstract: After a short review on gravitational waves, I will discuss gravitational memory effects in GR and its relationship to asymptotic symmetries. Then, I will study Brans-Dicke theory where a novel memory effect shows up, known as the breathing memory . This memory has no obvious symmetry interpretation. I will show that such a symmetry interpretation in hidden in the formulation of the dialton field in terms of a dual two-form field.

This result was extended by Deconinck to the generalized Fermat equation of the form Ax^p + By^p + Cz^p = 0, where A, B, C are odd integers belonging to a totally real field. Later Sengun and Siksek showed that the asymptotic FLT holds over number fields assuming standard modularity conjectures. Combining their techniques we* show that the generalized Fermat's Last Theorem (GFLT) holds over number fields asymptotically assuming the standard conjectures. We also give three results which show the existence of fa ... |
