ITMP Seminar "Ghosts without runaway instabilities"

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Nov 8, 18:00 (Moscow time). It will be organised via Zoom.

Speaker: Prof. Cedric Deffayet, Ecole Normale Superieure, LPENS

Title: Ghosts without runaway instabilities

Abstract: I discuss simple mechanical models with a ghost interacting with a positive energy degree of freedom, and yet, the phase-space motion can be shown analytically and numerically to be fully stable. This is based on e-prints 2305.09631 [gr-qc] and 2108-06296 [gr-qc].

If you want to join the seminar please register here before 16:00, November 8 here.
