By This paper uses the novel quantile coherency approach to examine the tail dependence network of 49 international stock markets in the frequency domain. We find that geographical proximity and state of market development are important factors in stock markets networks.

In this study, we construct financial networks in which nodes are represented by assets and where edges are based on long-run correlations. We construct four networks (complete graph, a minimum spanning tree, a planar maximally filtered graph, and a threshold significance graph) and use three centrality measures (betweenness, eigenvalue centrality, and the expected force).

By We propose new cohomology theory for financial market. We perform analysis of financial tensor network for non-equilibrium state, with closeness centrality of a tensor field of partial correlation, with planar graph of Hilbert–Huang transform with hyperbolic spectrum of IMF. We detect the 2008 market crash for Thai SET50 Index Futures market.
Read moreWe provide the proof that the space of time series data is a Kolmogorov space with T0-separation axiom using the loop space of time series data. In our approach, we define a cyclic coordinate of intrinsic time scale of time series data after empirical mode decomposition.
Read moreAlmost all known econometric models applied on a long term basis on financial forex market do not work sufficiently. The reason is that transaction costs and arbitrage opportunity are not included, as this does not simulate the real financial markets.
Read moreWe have developed a novel prediction method based on string invariants. The method does not require learning but a small set of parameters must be set to achieve optimal performance.
Read moreOverwhelming majority of econometric models applied on a long term basis in the financial forex market do not work sufficiently well...
Read moreIn this paper we apply a new approach of string theory to the real financial market. The models are constructed with an idea of prediction models based on the string invariants (PMBSI)...
