An adaptive least-squares algorithm for the elliptic Monge–Ampère equation
We address the numerical solution of the Dirichlet problem for the two-dimensional elliptic Monge–Ampère equation using a least-squares/relaxation approach.

Freeform design of a two-reflector system to collimate and shape a point source distribution [PDF]
We present a method to design a freeform two-reflector system to collimate and shape a beam from a point source. An important generalization compared to previous research is that the output beam can be in an arbitrary direction.

Convergence of a regularized finite element discretization of the two-dimensional Monge-Ampère equation [PDF]
This paper proposes a regularization of the Monge–Ampère equation in planar convex domains through uniformly elliptic Hamilton–Jacobi–Bellman equations.

On some exact solutions of heavenly equations in four dimensions
Some new classes of exact solutions (so-called functionally invariant solutions) of the elliptic and hyperbolic complex Monge–Ampère equations and of the second heavenly equation are found. Besides, non-invariance of the found classes of solutions of the

The connection between the phase problem in optics, focusing of radiation, and the Monge–Kantorovich problem [PDF]
We discuss the use of variational principles for solving the phase problem in optics. In this paper, we consider the connection between four fundamental problems: the phase problem in optics, the inverse problem of focusing coherent radiation, the Monge –

Regularity of solutions to the quaternionic Monge-Ampère equation [PDF]
The regularity of solutions to the Dirichlet problem for the quaternionic Monge-Ampère equation is discussed. We prove that the solution to the Dirichlet problem is Hölder continuous under some conditions on the boundary values and the quaternionic Monge-

Singular structures in solutions to the Monge-Ampère equation with point masses
We construct new examples of Monge-Ampère metrics with polyhedral singular structures, motivated by problems related to the optimal transport of point masses and to mirror symmetry.

Global C2,α estimates for the Monge-Ampère equation on polygonal domains in the plane
:We classify global solutions of the Monge-Amp\\`ere equation $\\det D^2 u=1$ on the first quadrant in the plane with quadratic boundary data. As an application, we obtain global $C^\{2,\\alpha\}$ estimates for the non-degenerate Monge-Amp\\`ere equation
