"Einstein Equations from Geometric Viewpoint"
By
Abstract: The
Einstein Field Equations in General Relativity describe how the space-time must
be curved in the presence of matter and energy. These equations are of utmost
importance in mathematics as well: in vacuum, the solutions of these equations
are the metrics with "constant Ricci curvature", and thus, they give
a canonical preferred "shape" to the underlying manifold. In this
talk, I will give a survey of results on Einstein metrics, present lots of
examples (Calabi-Yau Manifolds, Gibbons-Hawking
Gravitational Instantons) and obstructions to their existence,
and indicate why these metrics are significant in the study of geometry.
