From sectorial coarse graining to extreme coarse graining of S&P 500 correlation matrices
Manan Vyas, M. Mijaíl Martínez-Ramos, Parisa Majari +1
Starting from the Pearson Correlation Matrix of stock returns and from the desire to obtain a reduced number of parameters relevant for the dynamics of a financial market, we propo…
Identifying States of a Financial Market
Michael C. Münnix, Takashi Shimada, Rudi Schäfer +3
The understanding of complex systems has become a central issue because complex systems exist in a wide range of scientific disciplines. Time series are typical experimental result…
Symmetry breaking: A tool to unveil the topology of chaotic scattering with three degrees of freedom
C. Jung, W. P. Karel Zapfe, O. Merlo +1
We shall use symmetry breaking as a tool to attack the problem of identifying the topology of chaotic scatteruing with more then two degrees of freedom. specifically we discuss the…
Quantum and classical echoes in scattering systems described by simple Smale horseshoes
C. Jung, C. Mejia-Monasterio, T. H. Seligman
We explore the quantum scattering of systems classically described by binary and other low order Smale horseshoes, in a stage of development where the stable island associated with…
A Finite Element Algorithm for High-Lying Eigenvalues and Eigenfunctions with Homogeneous Neumann and Dirichlet Boundary Conditions
G. Baez, F. Leyvraz, R. A. Mendez-Sanchez +1
We present a finite element algorithm that computes eigenvalues and eigenfunctions of the Laplace operator for two-dimensional problems with homogeneous Neumann or Dirichlet bounda…
