In this note we discuss the geometric foundations of gravitational theories. The central role of linear connections on space-time is emphasized. The classification of Lagrangian theories in purely affine, metric-affine and purely metric theories is discussed, together with the definition of th gravitational field.

Abstract
In this note we discuss the geometric foundations of gravitational theories. The central role of linear connections on space-time is emphasized. The classification of Lagrangian theories in purely affine, metric-affine and purely metric theories is discussed, together with the definition of th gravitational field.
