The El Nino events: their classification and scale-invariance laws
fractal geometry scale-invariance MEI, El Nino, SOC
2015/8/28
Many point indices have been developed to describe the El Niño/Southern Oscillation but the Multivariate ENSO Index (MEI) is considered the most representative since it links different meteorolog...
Internal Quadratic Invariance and Decentralized Control
Decentralized Control Quadratic Invariance
2015/6/19
For decentralized control systems with quadratically invariant information constraints, the set of achievable closed-loop maps is affine, and thus the associated minimum-norm controller synthesis prob...
GAUGE NON-INVARIANCE AS TESTS OF EMERGENT GAUGE SYMMETRY
Incentives emergency plan is symmetrical the underlying basic theory lorentz invariance of gravity field
2014/12/18
We motivate the concept of emergent gauge symmetry and discuss ways that this concept can be tested. The key idea is that if a symmetry is emergent, one should look for small violations of this symmet...
Breaking diffeomorphism invariance and tests for the emergence of gravity
General relativity violates diffeomorphism invariance disrupting sex match the test parameters Newton formalism
2014/12/18
If general relativity is an emergent phenomenon, there may be small violations of diffeomorphism invariance. We propose a phenomenology of perturbatively small violations of general relativity by the ...
Notes on the Schwinger model: regularization and gauge invariance
the Schwinger model regularization and gauge invariance Mathematical Physics
2012/6/21
The point-splitting computation of the gauge invariant Hamiltonian for the Schwinger model on the circle in a positive energy representation is presented.
Approximate invariance of metabolic energy per synapse during development in mammalian brains
Synaptogenesis brain metabolism model synaptic density firing rate
2012/5/2
During mammalian development the cerebral metabolic rate correlates qualitatively with synaptogenesis, and both often exhibit bimodal temporal profiles. Despite these non-monotonic dependencies, it is...
A new geometric °ow with rotational invariance
System of hyperbolic-parabolic equations rotational invariance global smooth solution time-asymptotic behavior hypersurface
2018/4/19
In this paper we introduce a new geometric flow with rotational invariance and prove that, under this kind of flow, an arbitrary smooth closed contractible hypersurface in the Euclidean space Rn+1 (n...
Limit-circle invariance of non-symmetric discrete Hamiltonian systems

2011/10/12
In this paper, we first give the related important Lemmas, and after discusses the non-symmetric discrete Hamiltonian system, and obtain the limit-circle invariance theorem. The main results contain c...
Abstract: This manuscript was originally created for and printed in the "Proceedings of seminar on unified theories of elementary particles" held in Feldafing Germany from July 5 to 16 1965 under the ...
An Invariance Principle for the Tagged Particle Process in Continuum with Singular Interaction Potential
Diffusion processes interacting continuous particle systems random environment invariance principles
2011/9/1
Abstract: We consider the dynamics of a tagged particle in an infinite particle environment moving according to a stochastic gradient dynamics. For singular interaction potentials this tagged particle...
Violation of the Rotational Invariance in the CMB Bispectrum
Violation Rotational Invariance CMB Bispectrum
2011/9/27
We investigate a statistical anisotropy on the Cosmic Microwave Background (CMB) bispectrum which can be generated from the primordial non-Gaussianity induced by quantum fluctuations of a vector field...
Conformal invariance of curvature perturbation
Conformal invariance curvature perturbation
2011/10/18
We show that in the single component situation all perturbation variables in the comoving gauge are conformally invariant to all perturbation orders. Generally we identify a special time slicing, the ...

Controller Synthesis Robust Invariance Polynomial Dynamical Systems Linear Programming
2011/8/30
Abstract: In this paper, we consider a control synthesis problem for a class of polynomial dynamical systems subject to bounded disturbances and with input constraints. More precisely, we aim at synth...

Abstract: We present a 2+1 dimensional quantum gauge theory model with correlated fermions that is exactly solvable by bosonization. This model gives an effective description of partially gapped fermi...

We present a search for conformal invariance in vorticity isolines of two-dimensional compressible
turbulence. The vorticity is measured by tracking the motion of particles that float at the surface ...
