Stabilization of second order nonlinear equations with variable delay
Leonid Berezansky, Elena Braverman, Lev Idels
For a wide class of second order nonlinear non-autonomous models, we illustrate that combining proportional state control with the feedback that is proportional to the derivative o…
Stability conditions for scalar delay differential equations with a nondelay term
Leonid Berezansky, Elena Braverman
The problem considered in the paper is exponential stability of linear equations and global attractivity of nonlinear non-autonomous equations which include a non-delay term and on…
On stability of cooperative and hereditary systems with a distributed delay
Leonid Berezansky, Elena Braverman
We consider a system $\displaystyle \frac{dx}{dt}=r_1(t) G_1(x) \left[ \int_{h_1(t)}^t f_1(y(s))~d_s R_1 (t,s) - x(t) \right], \frac{dy}{dt}=r_2(t) G_2(y) \left[ \int_{h_2(t)}^t f_…
Boundedness and persistence of delay differential equations with mixed nonlinearity
Leonid Berezansky, Elena Braverman
For a nonlinear equation with several variable delays where the functions increase in some variable…
