On Hilbert extensions of Weierstrass' theorem with weights
Yamilet Quintana
In this paper we study the set of functions $\GG$-valued which can be approximated by $\GG$-valued continuous functions in the norm $L^\infty_{\GG}(I,w)$, where is a compact in…

Controllability of the Laguerre and the Jacobi Equations
Diomedes Barcenas, Hugo Leiva, Yamilet Quintana +1
In this paper we study the controllability of the controlled Laguerre equation and the controlled Jacobi equation. For each case, we found conditions which guarantee when such syst…
