Approximate null-controllability of discrete heat equations with potentials on lattices
Yann Bourroux, Philippe Jaming, Yunlei Wang
We investigate approximate null-controllability for semi-discrete heat equations on the lattice with a potential. By establishing spectral inequalities for the disc…

On the Three Balls Inequality for Discrete Schr{ö}dinger Operators on Certain Periodic Graphs
Philippe Jaming, Yann Bourroux, Aingeru Fernández-Bertolin
We investigate quantitative unique continuation properties for discrete magnetic Schr{ö}dinger operators in certain periodic graphs. This unique continuation property will be quan…
