Extremum conditions for functionals involving higher derivatives of several variable vector valued functions
Mahouton Norbert Hounkonnou, Pascal Dkengne Sielenou
This paper addresses both necessary and relevant sufficient extremum conditions for a variational problem defined by a smooth Lagrangian, involving higher derivatives of several va…
Factorization of linear and nonlinear differential operators: necessary and sufficient conditions
Mahouton Norbert Hounkonnou, Pascal Dkengne Sielenou
An algebraic approach for factorizing nonlinear partial differential equations (PDEs) and systems of PDEs is provided. In the particular case of second order linear and nonlinear P…
Classes of second order nonlinear differential equations reducible to first order ones by variation of parameters
Mahouton Norbert Hounkonnou, Pascal Alain Dkengne Sielenou
The method of parameter variation for linear differential equations is extended to classes of second order nonlinear differential equations. This allows to reduce the latter to fir…
