Optimal control of a dengue model with cross-immunity
Mathematical modelling of a dengue epidemic with two serotypes including a temporary cross-immunity yields a nonlinear system consisting of ordinary...

On bihom-gerstenhaber algebras up to homotopy
In the current research paper, we define and investigate the concept of BiHom-Gerstenhaber algebra. This algebraic structure is defined by two linear...

Pseudo-differential operators in several p-adic variables and sub-Markovian semigroups
This article marks the inaugural exploration of certain classes of negative or positive definite functions in several p -adic variables. Associated...

On two conjectures related to cubic residues
In a recent paper by Yuan and Zhang (Indian J. Pure Appl. Math. 54(3):806–815, 2023), the authors put forward two conjectures regarding

Correction of nonmonotone trust region algorithm based on a modified diagonal regularized quasi-Newton method
In this paper, a new appropriate diagonal matrix estimation of the Hessian is introduced by minimizing the Byrd and Nocedal function subject to the...

Bounds of the Solution Set to the Polynomial Complementarity Problem
In this paper, we investigate bounds of solution set of the polynomial complementarity problem. When a polynomial complementarity problem has a...

Prevention and control of Ebola virus transmission: mathematical modelling and data fitting
The Ebola virus disease (EVD) has been endemic since 1976, and the case fatality rate is extremely high. EVD is spread by infected animals,...

Positivity and matrix inequalities: some reminiscences of K. R. Parthasarathy
One of K. R. Parthasarathy’s major and abiding interests was the theory of positive definite functions and especially its relation to classical and...

Convex Predictor–Nonconvex Corrector Optimization Strategy with Application to Signal Decomposition
Many tasks in real life scenarios can be naturally formulated as nonconvex optimization problems. Unfortunately, to date, the iterative numerical...

Existence of Nontrivial Solutions to a Critical Fourth-Order Kirchhoff Type Elliptic Equation
In this paper, a critical fourth-order Kirchhoff type elliptic equation with a subcritical perturbation is studied. The main feature of this problem...

Global Well-Posedness and Exponential Decay of Strong Solution to the Three-Dimensional Nonhomogeneous Bénard System with Density-Dependent Viscosity and Vacuum
In this paper, we are concerned with the three-dimensional nonhomogeneous Bénard system with density-dependent viscosity in bounded domain. The...

Upper bound for the second and third Hankel determinants of analytic functions associated with the error function and q-convolution combination
Recently, El-Deeb and Cotîrlă (Mathematics 11:11234834,
2023 ) used the error function together with a q -convolution to introduce a new operator. By... -
Parabolicity and Cheeger’s constant on graphs
Herein we study p -parabolicity on graphs. We prove that if a uniform graph satisfies the (Cheeger) isoperimetric inequality, then it is non- p -paraboli...
