Correlations of stocks in time have been widely studied. Both the random matrix theory approach and the graphical visualization of so-called minimum spanning trees show the clustering of stocks according to industrial sectors. Studying the correlation between stocks traded in markets of...

We consider a generalization of the Heath-Jarrow-Morton model for the term structure of interest rates where the forward rate is driven by Paretian fluctuations. We derive a generalization of Ito's lemma for the calculation of a differential of a Paretian stochastic variable and use it to derive...

An understanding of the behaviour of financial assets and the evolution of economies has never been as important as today. This book looks at these complex systems from the perspective of the physicist. So called 'econophysics' and its application to finance has made great strides in recent...
