The Principle of Nonuniformity Three Structural Quantities, a Master Equation Graded in Four Layers, and the Correct Classification of Aggregation Limits

Abstract: The macroscopic phenomenological apparatus of open flow-through systems — an income-minus-expenditure master equation, a gradient-flow relaxation, and a quasi-potential landscape — is usually posed as a set of postulates. This paper assembles that apparatus into a diagn...

A Correction: The Variational Object for Complex-System Emergence Is a Large-Deviation Action, Not a Mechanical Lagrangian

Abstract Version 1 of this paper claimed a Least Action Principle for Complex Systems Emergence: that the evolution of any complex system extremizes a complexity action functional built on a Lagrangian of the form kinetic minus tension minus shock plus driving, and that the exist...

Cross-Scale Critical Synchronization in Driven Multi-Layer Systems:Thresholds, Zero-Parameter Predictions, and the Non-Normal Variance Trap

Abstract When the coupling between two adjacent layers of a driven system crosses a threshold, their critical slowing down phase-locks: the layers no longer approach instability independently but share a single diverging slow mode. This paper takes the threshold formula from elem...
