Bilinear controllability for the linear KdV-Schr{ö}dinger equation
Rémi Buffe, Alessandro Duca, Hugo Parada
We study the controllability of a linear KdV-Schr{ö}dinger equation on the one-dimensional torus via purely imaginary bilinear controls. Considering controls spanning a suitable f…

Small-time estimates for a real moment problem with two-term Weyl spectral law
Rémi Buffe, Alessandro Duca
In this work, we first study the solvability of moment problems involving real exponentials and provide explicit estimates of the associated control cost. The result holds when the…
