approximately 25% of people died as they got infected [1, 2]. COVID-19 shows the
symptoms of dry cough, fever, fatigue, breathing difficulties and bilateral lung infiltration.[...] …

In this paper, we present sufficient conditions to ensure the stochastic asymptotic stability of
the zero solution for a specific type of fourth-order stochastic differential equation (SDE) with …

In this paper a novel class of fourth order functional differential equations is discussed. By
reducing the fourth order functional differential equation to system of first order, a suitable …

The key task of this paper is to investigate a nonlinear fourth-order delay differential
equation. By virtue of the fixed point theory and the Green's functions method, we establish …

In this paper a novel class of fourth order functional differential equations is discussed. By

This paper deals the HBV infections using Homotopy Perturbation Method, Using
Mathematical modeling for the three compartments such as T, I andV Where T denotes the …

Right now we take a gander at the diagnostic and numerical reenactments of Dengue fever
and perceive its best features close by their execution for various circumstances. Dengue is …

We discuss the model for Swine flu transmission. We obtain to find the equilibrium points of
the given swine flu model with the stability analysis and the endemic equilibrium is derived …

In this paper the oscillatory behaviour of higher order nonlinear delay differential equation
theorems and examples are investigated. Some new oscillatory main results of higher order …

He's variational iteration method is used to give approximate analytical solutions of
nonlinear differential equations arising in conjoint normal-tumor cells. The convergence …
