This review presents an overview of the current research in kinetic exchange models for opinion formation a society. The begins with brief introduction to previous and subsequently provides in-depth discussion progress achieved Biswas-Chatterjee-Sen model proposed 2012, also known as BChS some later publications. unique feature is its inclusion negative interaction between agents. covers variou...

The author and director of the film Bridge (2016), Amit R. Biswas, reflects on process film-making, using strategies that deal with self (and, therefore, social) transformation through art. In a sort inner confession monologue, he delves not only into more anecdotal part logistics economic tour-de-force problems producing involve; but also, interestingly, in causes, nuances, psychological detai...

The oscillatory motion in nonlinear nanolattices having different interatomic potential energy functions is investigated. Potential energies such as the classical Morse, Biswas – Hamann and modified Lennard Jones potentials are considered interaction between atoms one-dimensional nanolattices. Noteworthy phenomena obtained with a chain, for each of considered. generalized governing system equat...

The system of coupled generalized nonlinear Schrodinger equations describing the propagation pulses in a birefringent fiber is considered. Using traveling wave reduction constraints on model parameters are found, which compatibility conditions for system. Under found parameters, solutions form periodic and solitary waves obtained.

Given a Henselian and Japanese discrete valuation ring $A$ flat projective $A$-scheme $X$, we follow the approach of Biswas-dos Santos to introduce full subcategory coherent modules on $X$ which is then shown be Tannakian. We prove that, under normality generic fibre, associated affine group pro-finite in strong sense (so that its functions Mittag-Leffler $A$-module) it classifies finite torsor...

We consider the nonlinear Neumann problem for fully elliptic PDEs on a quadrant. establish comparison theorem viscosity sub- and supersolutions of problem. The crucial argument in proof is to build $C^{1,1}$ test function which takes care boundary condition. A similar has been treated general $n$-dimensional orthant by Biswas et al. [SIAM J. Control Optim., 55 (2017), pp. 365--396], where funct...
