Incidence preserving transformations are geometric mappings that maintain the incidence relationships between points and hyperplanes, meaning if a point lies on a hyperplane before the transformation, it continues to lie on that hyperplane after the transformation. This concept is crucial in understanding duality, where points and hyperplanes can be interchanged while preserving their relationships. Such transformations help in analyzing configurations in geometry by allowing a shift in perspective without altering the fundamental relationships between the elements involved.
