Determinism vs. Indeterminism: A Representational Issue

Published:Dec 27, 2025 09:41
1 min read
ArXiv

Analysis

This paper challenges the traditional view of determinism and indeterminism as fundamental ontological properties in physics. It argues that these are model-dependent features, and proposes a model-invariant ontology based on structural realism. The core idea is that only features stable across empirically equivalent representations should be considered real, thus avoiding problems like the measurement problem and the conflict between determinism and free will. This approach emphasizes the importance of focusing on the underlying structure of physical systems rather than the specific mathematical formulations used to describe them.
Reference

The paper argues that the traditional opposition between determinism and indeterminism in physics is representational rather than ontological.

Analysis

This paper challenges the common interpretation of the conformable derivative as a fractional derivative. It argues that the conformable derivative is essentially a classical derivative under a time reparametrization, and that claims of novel fractional contributions using this operator can be understood within a classical framework. The paper's importance lies in clarifying the mathematical nature of the conformable derivative and its relationship to fractional calculus, potentially preventing misinterpretations and promoting a more accurate understanding of memory-dependent phenomena.
Reference

The conformable derivative is not a fractional operator but a useful computational tool for systems with power-law time scaling, equivalent to classical differentiation under a nonlinear time reparametrization.

Analysis

This paper presents a novel semi-implicit variational multiscale (VMS) formulation for the incompressible Navier-Stokes equations. The key innovation is the use of an exact adjoint linearization of the convection term, which simplifies the VMS closure and avoids complex integrations by parts. This leads to a more efficient and robust numerical method, particularly in low-order FEM settings. The paper demonstrates significant speedups compared to fully implicit nonlinear formulations while maintaining accuracy, and validates the method on a range of benchmark problems.
Reference

The method is linear by construction, each time step requires only one linear solve. Across the benchmark suite, this reduces wall-clock time by $2$--$4\times$ relative to fully implicit nonlinear formulations while maintaining comparable accuracy.
