Explicit traces of functions on Sobolev spaces and quasi-optimal linear interpolators

Daniel Estévez

Let $Λ \subset R$ be a strictly increasing sequence. For $r = 1, 2$ , we give a simple explicit expression for an equivalent norm on the trace spaces $W_{p}^{r} (R) ∣_{Λ}$ , $L_{p}^{r} (R) ∣_{Λ}$ of t…

Decay rate estimations for linear quadratic optimal regulators

Daniel Estévez, Dmitry Yakubovich

Let $u (t) = - F x (t)$ be the optimal control of the open-loop system $x^{'} (t) = A x (t) + B u (t)$ in a linear quadratic optimization problem. By using different complex variable arguments, we g…
