Reality as a Constraint-Invariant Structure: A Projection-Based Reformulation of Observed Existence

Key Points

This work aims to redefine reality through a projection-based framework that emphasizes structural invariance under constraints.
Developed a core formulation R = ⋂_i Pi_i(S) defining reality as invariant across projections.
Integrated principles from projection theory, structural realism, systems theory, and information theory.
Explored implications for observable reality, measurement, and geometric properties in complex systems.
Defined reality as an invariant core across diverse projections, highlighting its constraint-dependent nature.
Demonstrated that measurement fundamentally reduces complexity, impacting understanding of objecthood and geometry.
Proposed that observational consistency shapes the effective reality experienced.

Abstract

Reality as a Constraint-Invariant Structure introduces a projection-based framework for understanding observed existence, structural invariance, and epistemic accessibility under constrained observation systems. The paper defines reality not as a directly accessible external substrate, but as the invariant structure that survives across all admissible observational projections of an inaccessible full system state. Core formulation: R = ⋂ᵢ Piᵢ (S) where: S = inaccessible full system state, Piᵢ = admissible observation operators, R = invariant structural core across projection diversity. The framework combines: projection theory, structural realism, systems theory, information theory, fixed-point invariance, and the Structural Depth framework developed by H. I. Güven. The paper further proposes that: observable reality is constraint-dependent, measurement is fundamentally reductive, geometry and objecthood emerge from invariant accessibility structures, and observational consistency generates effective reality. This work is part of the broader Market Alchemy research framework focused on: structural decision systems, constraint-based organization, accessibility dynamics, spectral structure, and invariant behavior across complex systems and financial markets.
