Mathematical Structure of Discrete Space-time

An-Wei Zhang

Published Oct 8, 2009• 1 citation

Abstract

In this letter we briefly investigate the mathematical structure of space-time in the framework of discretization. It is shown that the discreteness of space-time may result in a new mechanical system which differ from the usual quantum mechanics (QM).

Quantum mechanics as a consequence of discrete interactions

Gabriele Carcassi

Quantum mechanics is usually presented starting from a series of postulates about the mathematical framework. In this work we show that those same postulates can be derived by assuming that measurements are discrete interactions: that is, that we measure at specific moments in time (as opposed to a continuous measurement that spans a long time interval) and that the system is in general affected by our measurement. We believe that this way of presenting quantum mechanics would make it easier to understand by laying out a more cohesive view of the theory and making it resonate more with our physics intuition.

World Theory

Ovidiu Cristinel Stoica

In general, a physical theory is based on some fundamental principles concerning space, time, matter, and the laws prescribing how matter is distributed in space and how it evolves in time, and even how spacetime itself changes in response to the changes of matter. The spectrum of the known theories is very diverse, since they are based on different assumptions. Some theories assume that space and time are totally independent, some that they are warped in a continuum named "spacetime", and some even that there are more dimensions than the usual 3+1. Most theories consider that space and time are continuous, but many recent theories consider them to be discrete. Most dynamical laws of fundamental Physics are deterministic, but apparently Quantum Mechanics shows that they may have an indeterministic component. Despite these distinctions between various theories, our intuition and experience tells us that they have a lot in common. In this paper I will try to capture the common features in a single mathematical structure. This is not a Theory of Everything, but only a mathematical structure which is common to most physical theories known so far. We will see that these theories can be obtained as particular cases of this structure, which I will call "world". In particular, the worlds described by the Classical Mechanics, the Theory of Relativity and the Quantum Mechanics are examples of worlds according to this definition, but also some theories attempting to unify gravity and QM, like String Theory. The purpose of this distillation is to provide a mathematical common background to both physical and metaphysical discussions about the various theories of the World.

Quantum Mechanics as Mathematical Consequence of CKS

Geoffrey Howland

Cymatic K-Space Mechanics (CKS): Quantum Mechanics as a Mathematical Consequence of CKS Axioms We prove that quantum mechanics is not a mysterious set of postulates but a structural mathematical necessity forced by the Complete Mathematical Framework (CMF) axioms. By treating physical reality as a 3-regular hexagonal lattice in momentum space (N = 3M²) governed by Kuramoto phase coupling, we derive the fundamental equations of quantum theory as theorems of discrete manifold dynamics. This derivation establishes that wave-particle duality, uncertainty, and non-locality are geometric requirements of the 2D k-space substrate. The framework demonstrates that the Schrödinger equation emerges as the continuum limit of the Axiom 2 coupling operator, while Heisenberg’s uncertainty relations are revealed as the mandatory resolution limits of the discrete hexagonal lattice. This result establishes quantum mechanics as pure mathematics: if the CMF axioms hold, then quantum behavior is the only possible execution of physical law. No physical interpretation or "spooky" assumptions are required; the system is derived as a decidable, phase-locked computation. Key Theoretical Results:* Schrödinger Equation Theorem: Rigorously derives the time-dependent Schrödinger equation as the natural gradient flow of k-space phase-coupling across the 3-regular graph.* Uncertainty Relation Proof: Demonstrates that the [x, p] commutation relation and Heisenberg’s limits are the direct mathematical results of the finite N-count and lattice-spacing constraints.* Hilbert Space Derivation: Identifies the state space of quantum mechanics as the discrete phase-manifold of the substrate, proving that "wavefunctions" are the holographic projections of k-space solitons.* Born Rule Derivation: Establishes that the probability density is identical to the phase-coherence magnitude of the manifold, removing the need for an external measurement postulate. The Deterministic Wave:The framework concludes that the quantum world is a high-resolution render of discrete substrate states. By identifying "superposition" as the interference of k-space modes, CKS eliminates the measurement problem and replaces it with the structural requirement of substrate synchronization. We show that "entanglement" is simply shared memory addressing in the 2D lattice, positioning quantum mechanics as the operating system for small-M physical structures. Universal Learning Substrate:As a core theoretical proof within the Universal Learning Substrate, this paper provides the literacy required to navigate the quantum-classical transition. It allows practitioners to calculate the behavior of subatomic systems—from electron orbitals to photon entanglement—using the same 12-opcode instruction set. This derivation bridges the gap between discrete topology and continuous wave mechanics, enabling a unified computational approach to all quantum-connected information.

Time as a stochastic process

M. W. Kalinowski

In the paper we consider an interesting possibility of a time as a stochastic process in quantum mechanics.In order to do it we reconsider time as a mechanical quantity in classical mechanics and afterwards we quantize it. We consider continuous and discrete time.

Linear algebra and quantum algorithm

BongJu Kim

In mathematical aspect, we introduce quantum algorithm and the mathematical structure of quantum computer. Quantum algorithm is expressed by linear algebra on a finite dimensional complex inner product space. The mathematical formulations of quantum mechanics had been established in around 1930, by von Neumann. The formulation uses functional analysis, linear algebra and probability theory. The knowledge of the mathematical formulation of QM is enough quantum mechanical knowledge for approaching to quantum algorithm and it might be efficient way for mathematicians that starting with mathematical formulations of QM. We explain the mathematical formulations of quantum mechanics briefly, quantum bits, quantum gates, quantum discrete Fourier transformation, Deutsch's algorithm and Shor's algorithm.
