Network-centric indicators for fragility in global financial indices

1 code implementation29 Jan 2021 Areejit Samal, Sunil Kumar, Yasharth Yadav, Anirban Chakraborti

Over the last two decades, financial systems have been studied and analysed from the perspective of complex networks, where the nodes and edges in the network represent the various financial components and the strengths of correlations between them.

Network geometry and market instability

no code implementations25 Sep 2020 Areejit Samal, Hirdesh K. Pharasi, Sarath Jyotsna Ramaia, Harish Kannan, Emil Saucan, Jürgen Jost, Anirban Chakraborti

The complexity of financial markets arise from the strategic interactions among agents trading stocks, which manifest in the form of vibrant correlation patterns among stock prices.

Comparative analysis of two discretizations of Ricci curvature for complex networks

no code implementations20 Dec 2017 Areejit Samal, R. P. Sreejith, Jiao Gu, Shiping Liu, Emil Saucan, Jürgen Jost

We have performed an empirical comparison of two distinct notions of discrete Ricci curvature for graphs or networks, namely, the Forman-Ricci curvature and Ollivier-Ricci curvature.

Forman curvature for complex networks

1 code implementation1 Mar 2016 R. P. Sreejith, Karthikeyan Mohanraj, Jürgen Jost, Emil Saucan, Areejit Samal

We adapt Forman's discretization of Ricci curvature to the case of undirected networks, both weighted and unweighted, and investigate the measure in a variety of model and real-world networks.
