The Martin boundary of the Directed Landscape
Firas Rassoul-Agha, Mikhail Sweeney
In the directed landscape, the Martin boundary coincides with the horofunction boundary. We show that functions in this boundary are precisely the eternal solutions possessing a sp…

Shocks, instability, and the twenty networks of infinite geodesics in the Directed Landscape
Firas Rassoul-Agha, Mikhail Sweeney
For stochastic Hamilton-Jacobi (SHJ) equations, instability points are the space-time locations where two eternal solutions with the same asymptotic velocity differ. Another fundam…

Shocks and instability in Brownian last-passage percolation
Firas Rassoul-Agha, Mikhail Sweeney
For stochastic Hamilton-Jacobi (SHJ) equations, instability points are the space-time locations where two eternal solutions with the same asymptotic velocity differ. Another crucia…
