Some identification problems for integro-differential operator equations

Alfredo Lorenzi, Alexander Ramm

We consider, in a Hilbert space $H$ , the convolution integro-differential equation $u^{''} (t) - h * A u (t) = f (t)$ , $0 \leq t \leq T$ , $h * v (t) = \int_{0}^{t} h (t - s) v (s) d s$ , where $A$ is a linear clos…

Property C for ODE and applications

Alexander G. Ramm

An overview of the authors results is given. Property C for ODE is defioned, It is proved that the pair of Sturm-Liouville operators has property C. This property is applied to man…
