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 ...

ORDINARY DIFFERENTIAL EQUATIONS OF EVEN ORDER WITH INTEGRAL CONDITIONS
Доклады Российской академии наук. Математика, информатика, процессы управления / Doklady MathematicsWe consider an even-order ordinary differential operator with a spectral parameter and integral conditions. An a priori estimate of the solutions to the problem is obtained for sufficiently large values of the spectral parameter. The discreteness and the sectoral structure of the spectrum of the corresponding operators are proved.
