Some Nonlinear Equations with Double Solutions: Soliton and Chaos
Yi-Fang Chang
The fundamental characteristics of soliton and chaos in nonlinear equation are completely different. But all nonlinear equations with a soliton solution may derive chaos. While onl…
Multiply Connected Topological Economics, Confidence Relation and Political Economy
Yi-Fang Chang
Using the similar formulas of the preference relation and the utility function, we propose the confidence relations and the corresponding influence functions that represent various…
Gravitational Collapse and Radiation of Grand Unified Theory
Yi-Fang Chang
The infinite gravitational collapse of any supermassive stars should pass through an energy scale of the grand unified theory (GUT). After nucleon-decays, the supermassive star wil…
Possible Outlet of Test on Violation of Pauli Exclusion Principle
Yi-Fang Chang
The present experimental tests have proved high precisely the validity of the Pauli exclusion principle (PEP) in usual cases. The future experiments should be combined widely with…
Perfect Structure of the Special Relativity, Superluminal, Neutrino-Photon Mass and New Entangled Interaction
Yi-Fang Chang
First, some superluminal phenomena and experiments are introduced briefly. Next, based on the basic principles of the special relativity, the Lorentz transformation (LT) with small…
Fractal Relativity, Generalized Noether Theorem and New Research of Space-Time
Yi-Fang Chang
First, let the fractal dimension D=n(integer)+d(decimal), so the fractal dimensional matrix was represented by a usual matrix adds a special decimal row (column). We researched tha…
The Extensive Special Relativity and Comment on Local Lorentz Transformation in Varying Speed of Light Theory
Yi-Fang Chang
It is proved that local Lorentz transformations for different systems cannot derive varying speed of light. Based on the special relativity principle, an invariant speed is necessa…
Negative Matter, Repulsion Force, Dark Matter, Phantom and Theoretical Test ----Their Relations with Inflation Cosmos and Higgs Mechanism
Yi-Fang Chang
First, dark matter is introduced. Next, the Dirac negative energy state is rediscussed. It is a negative matter with some new characteristics, which are mainly the gravitation each…
Query on Negative Temperature, Internal Interactions and Decrease of Entropy
Yi-Fang Chang
After negative temperature is restated, we find that it will derive necessarily decrease of entropy. Negative temperature is based on the Kelvin scale and the condition dU>0 and dS…
Universal 2+1-Dimensional Plane Equations in General Relativity and Evolutions of Disk Nebula
Yi-Fang Chang
The general relativity is the base for any exact evolutionary theory of large scale structures. We calculate the universal 2+1-dimensional plane equations of gravitational field in…
