Tracking controllability for finite-dimensional linear systems
Sebastián Zamorano, Enrique Zuazua
This paper develops a functional-analytic characterization of output tracking controllability for finite-dimensional linear systems. By formulating tracking as the surjectivity of…

The Coercivity Gap in Neural PDE Solvers: Parameter Escape and Functional Convergence
Enrique Zuazua
We study neural approximation of elliptic PDE solutions from a variational perspective. The central point is the distinction between the geometry of neural parameters and the conve…

Tracking controllability for the heat equation
Jon Asier Bárcena Petiso, Enrique Zuazua
We study the tracking or sidewise controllability of the heat equation. More precisely, we seek for controls that, acting on part of the boundary of the domain where the heat proce…
