Infinite horizon impulse control problem with jumps and continuous switching costs

Rim Amami, Monique Pontier, Hani Abidi

The purpose of this paper is to show the existence results for adapted solutions of infinite horizon doubly reflected backward stochastic differential equations with jumps. These…

Nonessential sum graph of an Artinian ring

Bikash Barman, Kukil Kalpa Rajkhowa

The authors study the interdisciplinary relation between graph and algebraic structure ring defining a new graph, namely “non-essential sum graph”. The nonessential sum graph…

Finite extinction for a doubly nonlinear parabolic equation of fast diffusion type

Md Abu Hanif Sarkar

The purpose of this paper is to find a doubly nonlinear parabolic equation of fast diffusion in a bounded domain.

Introduction of new Picard–S hybrid iteration with application and some results for nonexpansive mappings

Julee Srivastava

In this paper, Picard–S hybrid iterative process is defined, which is a hybrid of Picard and S-iterative process. This new iteration converges faster than all of Picard…

Geometric properties of the Bertotti–Kasner space-time

H.M. Manjunatha, S.K. Narasimhamurthy, Zohreh Nekouee

The purpose of this paper is to study the Bertotti–Kasner space-time and its geometric properties.

Robust numerical method for singularly perturbed differential equations having both large and small delay

Habtamu Garoma Debela

The purpose of this study is to develop stable, convergent and accurate numerical method for solving singularly perturbed differential equations having both small and large delay.

Some remarks on invariant lightlike submanifolds of indefinite Sasakian manifold

Samuel Ssekajja

The author considers an invariant lightlike submanifold M, whose transversal bundle tr…

Three-dimensional trans-Sasakian manifolds and solitons

Sudhakar Kumar Chaubey, Uday Chand De

The authors set the goal to find the solution of the Eisenhart problem within the framework of three-dimensional trans-Sasakian manifolds. Also, they prove some results of the…
