Unique continuation on planar graphs

Ahmed Bou-Rabee, William Cooperman, Shirshendu Ganguly

We show that a discrete harmonic function which is bounded on a large portion of a periodic planar graph is constant. A key ingredient is a new unique continuation result for the w…

Slow periodic homogenization for Hamilton-Jacobi equations

William Cooperman

Capuzzo-Dolcetta and Ishii proved that the rate of periodic homogenization for coercive Hamilton-Jacobi equations is $O (ε^{1/3})$ . We complement this result by constructi…
