A nonlinear inequality and evolution problems

A. G. Ramm

Assume that $g (t) \geq 0$ , and $g ˙ (t) \leq - γ (t) g (t) + α (t, g (t)) + β (t), t \geq 0; g (0) = g_{0}; g ˙ := \frac{d g}{d t},$ on any interval $[0, T)$ on which $g$ exists and ha…

Asymptotic stability of solutions to abstract differential equations

A. G. Ramm

An evolution problem for abstract differential equations is studied. The typical problem is: $$\dot{u}=A(t)u+F(t,u), \quad t\geq 0; \,\, u(0)=u_0;\quad \dot{u}=\frac {du}{dt}\qquad…
