An Improved FPT Algorithm for Computing the Interleaving Distance between Merge Trees via Path-Preserving Maps
Althaf P, Amit Chattopadhyay, Osamu Saeki
A merge tree is a fundamental topological structure used to capture the sub-level set (and similarly, super-level set) topology in scalar data analysis. The interleaving distance i…
A model of conflict and leadership: Is there a hawkish drift in politics?
Siddhartha Bandyopadhyay, Amit K Chattopadhyay, Mandar Oak
We analyze conflict between a citizenry and an insurgent group over a fixed resource such as land. The citizenry has an elected leader who proposes a division such that, the lower…
Cleaner Production in Optimized Multivariate Networks: Operations Management through a Roll of Dice
Amit K Chattopadhyay, Biswajit Debnath, Rihab El-Hassani +2
The importance of supply chain management in analyzing and later catalyzing economic expectations while simultaneously prioritizing cleaner production aspects is a vital component…
Economic inequality and mobility for stochastic models with multiplicative noise
Maria Letizia Bertotti, Amit K Chattopadhyay, Giovanni Modanese
In this article, we discuss a dynamical stochastic model that represents the time evolution of income distribution of a population, where the dynamics develop from an interplay of…
Poverty Index With Time Varying Consumption and Income Distributions
Amit K Chattopadhyay, T Krishna Kumar, Sushanta K Mallick
In a recent work (Chattopadhyay, A. K. et al, Europhys. Lett. {\bf 91}, 58003, 2010) based on food consumption statistics, we showed how a stochastic agent based model could repres…
Stochastic Effects in a Discretized Kinetic Model of Economic Exchange
M. L. Bertotti, A. K. Chattopadhyay, G. Modanese
Linear stochastic models and discretized kinetic theory are two complementary analytical techniques used for the investigation of complex systems of economic interactions. The form…
Dynamics of Spatial Heterogeneity in Landfill - A Stochastic Analysis
Amit Kumar Chattopadhyay, Prasanta Kumar Dey, Sadhan Kumar Ghosh
A landfill represents a complex and dynamically evolving structure that can be stochastically perturbed by exogenous factors. Both thermodynamic (equilibrium) and time varying (non…
A model for the optimal design of a supply chain network driven by stochastic fluctuations
Kostas Petridis, Amit K. Chattopadhyay, Prasanta K. Dey
Supply chain optimization schemes have more often than not underplayed the role of inherent stochastic fluctuations in the associated variables. The present article focuses on the…
Income Distribution Dependence of Poverty Measure: A Theoretical Analysis
Amit K Chattopadhyay, Sushanta K Mallick
With a new deprivation (or poverty) function, in this paper, we theoretically study the changes in poverty with respect to the `global' mean and variance of the income distribution…
