The Generalized Projective Riccati Equations Method for Solving Nonlinear Evolution Equations in Mathematical Physics

open access: yesAbstract and Applied Analysis, 2014
We apply the generalized projective Riccati equations method to find the exact traveling wave solutions of some nonlinear evolution equations with any-order nonlinear terms, namely, the nonlinear Pochhammer-Chree equation, the nonlinear Burgers equation ...

Position Dependent Mass Approach and Quantization for a Torus Lagrangian

open access: yes, 2016
We have shown that a Lagrangian for a torus surface can yield second order nonlinear differential equations using the Euler-Lagrange formulation. It is seen that these second order nonlinear differential equations can be transformed into the nonlinear ...

Integrable systems and modular forms of level 2 [PDF]

open access: yes, 2006
A set of nonlinear differential equations associated with the Eisenstein series of the congruent subgroup $\Gamma_0(2)$ of the modular group $SL_2(\mathbb{Z})$ is constructed. These nonlinear equations are analogues of the well known Ramanujan equations,

Nonlinear elliptic problems with the method of finite volumes

open access: yesDifferential Equations and Nonlinear Mechanics, 2006
We present a finite volume discretization of the nonlinear elliptic problems. The discretization results in a nonlinear algebraic system of equations.

Stability of Compacton Solutions of Fifth-Order Nonlinear Dispersive Equations

open access: yes, 2000
We consider fifth-order nonlinear dispersive $K(m,n,p)$ type equations to study the effect of nonlinear dispersion. Using simple scaling arguments we show, how, instead of the conventional solitary waves like solitons, the interaction of the nonlinear ...

Regularity and Sensitivity for McKean-Vlasov Type SPDEs Generated by Stable-like Processes [PDF]

open access: yes, 2018
In this paper we study the sensitivity of nonlinear stochastic differential equations of McKean-Vlasov type generated by stable-like processes. By using the method of stochastic characteristics, we transfer these equations to the non-stochastic equations

Painleve property and the first integrals of nonlinear differential equations

open access: yes, 2004
Link between the Painleve property and the first integrals of nonlinear ordinary differential equations in polynomial form is discussed. The form of the first integrals of the nonlinear differential equations is shown to determine by the values of the ...

Nonlinear deterministic equations in biological evolution

open access: yes, 2011
We review models of biological evolution in which the population frequency changes deterministically with time. If the population is self-replicating, although the equations for simple prototypes can be linearised, nonlinear equations arise in many ...
