Some Oscillation Criteria for Delay-Differential Equations of Even Order
SIAM Journal on Applied Mathematics, 1975The nonlinear delay-differential equation \[D^n \left[ {r( t )D^n y( t )} \right] + \sum\limits_{i = 1}^N {f_i } ( t )F_i \left[ {y_0 \left( {t - \tau _{i,0} ( t )} \right), \cdots ,y_{2n - 1} \left( {t - \tau _{i,2n - 1} ( t )} \right)} \right] = 0 \] is considered, where $y_k ( t ) = D^k y( t )$ for $k = 0, \cdots $ , $n - 1$ and $y_k ( t ) = D^{k ...

Differential algebra of the “even order Korteweg–De Vries equations”
Proceedings of the Edinburgh Mathematical Society, 1990In the quotient ring of differential polynomials modulo cubic terms the usual odd order hierarchy of Korteweg–de Vries equations can be supplemented by an even order hierarchy. The full (even and odd) sequence is generated by an Olver recursion operator of order one and any pair has zero bracket in the quotient ring.
