 Correlation (projective geometry)

In projective geometry, **correlation** is a concept that relates to the correspondence between points and lines (or planes) in projective spaces. Specifically, a correlation is a duality relation that systematically associates points with lines in such a way that certain geometric properties and configurations are preserved. ### Key Points about Correlation: 1. **Duality**: Projective geometry is characterized by its duality principle, meaning that many statements about points can be translated into statements about lines and vice versa.
