Correlation dynamics of Green functions
Nuclear Physics A, 1994 We generalize the methods used in the theory of correlation dynamics and establish a set of equations of motion for many-body correlation green's functions in the non-relativistic case. These non-linear and coupled equations of motion describe the dynamical evolution of correlation green's functions of different order and transparently show how many ...

Dynamic Asset Correlations Based on Vines [PDF]
SSRN Electronic Journal, 2015 We develop a new method for generating dynamics of conditional correlation matrices of asset returns. These correlation matrices are parameterized by a subset of their partial correlations, whose structure is described by a set of connected trees called “vine”.

Short-time dynamics with initial correlations [PDF]
Physical Review E, 2001 The short-time dynamics of correlated systems is strongly influenced by initial correlations giving rise to an additional collision integral in the non-Markovian kinetic equation. Exact cancellation of the two integrals is found if the initial state is thermal equilibrium which is an important consistency criterion. Analytical results are given for the

Inferring epigenetic dynamics from kin correlations [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Different cells in a clonal population can be in different phenotypic states, which persist for a few generations before switching to another state. Dynamics of switching between these states determines the extent of correlations between the phenotypes of related cells.

Nonequilibrium dynamic-correlation-length scaling method
, 2010 The finite-size scaling method in the equilibrium Monte Carlo(MC) simulations and the finite-time scaling method in the nonequilibrium-relaxation simulations are compromised.

Dynamic correlation models [PDF]
, 2014 One of the inputs required by investors, seeking to hold efficient portfolios, is the correlation between the securities to be included in the portfolio. Correlation estimates are required in most applications in finance including asset pricing models, capital allocation, risk management and option pricing and hedging.

Examination of Dynamic Correlation between Major Assets in Iran by DCC-GARCH Approach [PDF]
پژوهشهای اقتصادی, 2015 This study investigates the time-varying correlations among oil and coin prices, and exchange rate in Iran. Since investment is a key factor in economic growth and development, so the necessary funds should be provided and directed towards manufacturing ...

Electron correlation via frozen Gaussian dynamics [PDF]
The Journal of Chemical Physics, 2011 We investigate the accuracy and efficiency of the semiclassical frozen Gaussian method in describing electron dynamics in real time. Model systems of two soft-Coulomb-interacting electrons are used to study correlated dynamics under non-perturbative electric fields, as well as the excitation spectrum.
