2. Exploring new frontiers in strong-field gravity with gravitational waves

Dr Tanja Hinderer (university of amsterdam)

The recent detections of gravitational waves from merging black holes and neutron stars have established gravitational waves as a new cosmological messenger and opened unique opportunities for probing gravity and matter in unexplored regimes. I will discuss the basic physics of gravitational waves, the facilities and methods for detecting and interpreting the signals, and the remarkable...

1. συµπλεκτικoς and Complexus when two complexities (almost) meet

(joint work with Michel Cahen)
Symplectic geometry has its origins in the Hamiltonian formulation of classical mechanics. Complex geometry is on the crossroad of algebraic and differential geometry. In differential geometry it yields the notion of almost complex structures.
Kähler geometry is at the intersection of symplectic and complex geometry.
I shall recall examples and properties of...
