Computational approach to multifractal music
Paweł Oświęcimka, Jarosław Kwapień, Iwona Celińska +2
In this work we perform a fractal analysis of 160 pieces of music belonging to six different genres. We show that the majority of the pieces reveal characteristics that allow us to…
Asymmetric random matrices: What do we need them for?
Stanislaw Drozdz, Jaroslaw Kwapien, Andreas A. Ioannides
Complex systems are typically represented by large ensembles of observations. Correlation matrices provide an efficient formal framework to extract information from such multivaria…
The foreign exchange market: return distributions, multifractality, anomalous multifractality and Epps effect
Stanislaw Drozdz, Jaroslaw Kwapien, Pawel Oswiecimka +1
We present a systematic study of various statistical characteristics of high-frequency returns from the foreign exchange market. This study is based on six exchange rates forming t…
Structure and evolution of the foreign exchange networks
Jaroslaw Kwapien, Sylwia Gworek, Stanislaw Drozdz
We investigate topology and temporal evolution of the foreign currency exchange market viewed from a weighted network perspective. Based on exchange rates for a set of 46 currencie…
Scale free effects in world currency exchange network
A. Z. Gorski, S. Drozdz, J. Kwapien
A large collection of daily time series for 60 world currencies' exchange rates is considered. The correlation matrices are calculated and the corresponding Minimal Spanning Tree (…
Minimal Spanning Tree graphs and power like scaling in FOREX networks
A Z Gorski, S. Drozdz, J. Kwapien
Correlation matrices of foreign exchange rate time series are investigated for 60 world currencies. Minimal Spanning Tree (MST) graphs for the gold, silver and platinum are present…
