Two Fractal Overlap Time Series: Earthquakes and Market Crashes
Bikas K. Chakrabarti, Arnab Chatterjee, Pratip Bhattacharyya
We find prominent similarities in the features of the time series for the (model earthquakes or) overlap of two Cantor sets when one set moves with uniform relative velocity over t…
Three dimensional noncommutative bosonization
Rabin Banerjee, Subir Ghosh, T. Shreecharan
We consider the extension of the 2+1-dimensional bosonization process in Non-Commutative (NC) spacetime. We show that the large mass limit of the effective action obtained by integ…
A class of exactly solvable Schroedinger equation with moving boundary conditions
T. Jana, P. Roy
Using first and second order supersymmetry formalism we obtain a class of exactly solvable potentials subject to moving boundary conditions.
An Example of Constructing Versal Deformation for Leibniz Algebras
Ashis Mandal
In this work we compute a versal deformation of the three dimensional nilpotent Leibniz algebra over , defined by the nontrivial brackets and $[e_3,e_3]…
Local Equivalence of Rank-Two Quantum Mixed States
Sergio Albeverio, Shao-Ming Fei, Debashish Goswami
We investigate the equivalence of quantum mixed states under local unitary transformations. For a class of rank-two mixed states, a sufficient and necessary condition of local equi…
The Kolkata Paise Restaurant Problem and Resource Utilization
Anindya-Sundar Chakrabarti, Bikas K. Chakrabarti, Arnab Chatterjee +1
We study the dynamics of the "Kolkata Paise Restaurant problem". The problem is the following: In each period, N agents have to choose between N restaurants. Agents have a common r…
