Numerical Solutions of Duffing Van der Pol Equations on the Basis of Hybrid Functions

Advances in Mathematical Physics, 2023
In the present work, a new approximated method for solving the nonlinear Duffing-Van der Pol (D-VdP) oscillator equation is suggested. The approximate solution of this equation is introduced with two separate techniques. First, we convert nonlinear D-VdP

Generalizations of Integral Inequalities with Two Variables and their Applications

四川大学学报. 自然科学版, 2016
In this paper, we discuss a retarded nonlinear integral inequality with two variables. By using the techniques of monotonization and reducing the function outside the integral to constant, we give an estimation of the unknown function in the inequality ...

Necessity of a Wiener type condition for boundary regularity of quasiminimizers and nonlinear elliptic equations

, 2009
We use variational methods to obtain a pointwise estimate near a boundary point for quasisubminimizers of the p-energy integral and other integral functionals in doubling metric measure spaces admitting a p-Poincar, inequality.
