Geometry of commutes in the universality of percolating traffic flows
Sasan Ebrahimabadi, Ali Hosseiny, Jingfang Fan +1
Traffic congestion is a major problem in megacities which increases vehicle emissions and degrades ambient air quality. Various models have been developed to address the universal…
Response of the competitive balance model to the external field
Farideh Oloomi, Amir Kargaran, Ali Hosseiny +1
The competitive balance model was proposed as an extension of the structural balance theory, aiming to account for heterogeneities observed in real-world networks. In this model, d…
The structure of gene-gene networks beyond pairwise interactions
Nastaran Allahyari, Amir Kargaran, Ali Hosseiny +1
Despite its high and direct impact on nearly all biological processes, the underlying structure of gene-gene interaction networks is investigated so far according to pair connectio…
High participation ratio genes in the interaction network structure
Nastaran Allahyari, Ali Hosseiny, Nima Abedpour +1
Genes have specific functional roles, however, since they are dependent on each other, they can play a structural role within a network structure of their interactions. In this stu…
Mean-Field Solution for Critical Behavior of Signed Networks in Competitive Balance Theory
R. Masoumi, F. Oloomi, A. Kargaran +2
Competitive balance model has been proposed as an extension to the balance model to address the conflict of interests in signed networks arXiv:2001.04664 . In this model two differ…
Analysis of the Global Banking Network by Random Matrix Theory
Ali Namaki, Jamshid Ardalankia, Reza Raei +4
Since 2008, the network analysis of financial systems is one of the most important subjects in economics. In this paper, we have used the complexity approach and Random Matrix Theo…
Coupled criticality analysis of inflation and unemployment
Z. Koohi Lai, A. Namaki, A. Hosseiny +2
In this paper, we are interested to focus on the critical periods in the economy which are characterized by large fluctuations in macroeconomic indicators. To capture unusual and l…
Competitive Balance Theory: Modeling conflict of interest in a heterogeneous network
Farideh Oloomi, Razieh Masoumi, Kosar Karimipour +2
The dynamics of networks on Heider balance theory moves toward reducing the tension by constantly reevaluating the interactions to achieve a state of balance. Conflict of interest,…
Quartic Balance Theory: Global Minimum With Imbalanced Triangles
A. Kargaran, M. Ebrahimi, M. Riazi +2
Balance theory proposed by Heider for the first time modeled triplet interaction in a signed network, stating that relationships between two people, friendship or enmity, is depend…
Optimization of the post-crisis recovery plans in scale-free networks
Mohammad Bahrami, Narges Chinichian, Ali Hosseiny +2
General Motors or a local business, which one is better to be stimulated in post-crisis recessions, where government stimulation is meant to overcome recessions? Due to the budget…
Hysteresis of economic networks in an XY model
Ali Hosseiny, Mohammadreza Absalan, Mohammad Sherafati +1
Many-body systems can have multiple equilibria. Though the energy of equilibria might be the same, still systems may resist to switch from an unfavored equilibrium to a favored one…
Non-criticality of interaction network over system's crises: A percolation analysis
Amir Hossein Shirazi, Abbas Ali Saberi, Ali Hosseiny +2
Extraction of interaction networks from multi-variate time-series is one of the topics of broad interest in complex systems. Although this method has a wide range of applications,…
A geometrical imaging of the real gap between economies of China and the United States
Ali Hosseiny
GDP of China is about 11 trillion dollars and GDP of the United States is about 18 trillion dollars. Suppose that we know for the coming years, economy of the US will experience a…
Role of Intensive and Extensive Variables in a Soup of Firms in Economy to Address Long Run Prices and Aggregate Data
Ali Hosseiny, Mauro Gallegati
We review the production function and the hypothesis of equilibrium in the neoclassical framework. We notify that in a soup of sectors in economy, while capital and labor resemble…
Metastable Features of Economic Networks and Responses to Exogenous Shocks
Ali Hosseiny, Mohammad Bahrami, Antonio Palestrini +1
It has been proved that network structure plays an important role in addressing a collective behaviour. In this paper we consider a network of firms and corporations and study its…
Fractional Galilean Symmetries
Ali Hosseiny, Shahin Rouhani
We generalize the differential representation of the operators of the Galilean algebras to include fractional derivatives. As a result a whole new class of scale invariant Galilean…
Violation of Invariance of Measurement for GDP Growth Rate and its Consequences
Ali Hosseiny
The aim here is to address the origins of sustainability for the real growth rate in the United States. For over a century of observations on the real GDP per capita of the United…
Possible Central Extensions of Non-Relativistic Conformal Algebras in 1+1
Ali Hosseiny
We investigate possibility of central extension for non-relativistic conformal algebras in 1+1 dimension. Three different forms of charges can be suggested. A trivial charge for te…
Logarithmic Exotic Conformal Galilean Algebras
Malte Henkel, Ali Hosseiny, Shahin Rouhani
Logarithmic representations of the conformal Galilean algebra (CGA) and the Exotic Conformal Galilean algebra ({\sc ecga}) are constructed. This can be achieved by non-decomposable…
On Holographic Realization of Logarithmic GCA
Ali Hosseiny, Ali Naseh
We study 2-dimensional Logarithmic Galilean Conformal Algebra (LGCA) by making use of a contraction of Topologically Massive Gravity at critical point. We observe that using a naiv…
Logarithmic Correlators in Non-relativistic Conformal Field Theory
Ali Hosseiny, Shahin Rouhani
We show how logarithmic terms may arise in the correlators of fields which belong to the representation of the Schrodinger-Virasoro algebra (SV) or the affine Galilean Conformal Al…
