Generalizing classical notions, we define configurations as triples of schemes over a base and show that the moduli functor of representations into a geometric configuration is representable by a scheme. We construct fine moduli spaces for nondegenerate representations and realizations, and study their behavior under deformation. Applications include a modern perspective on Mnëv–Sturmfels universality and connections to classical projective theorems, highlighting new interactions between configuration theory, moduli spaces, and algebraic geometry.application/pdfen-USCC BYAlgebraic GeometryArrangementsConfiguration SpacesConfigurationsIncidence GeometriesModuli SpacesMathematicsMathematicsThesis
