A fully nonlinear generalized Monge-Ampere PDE on a torus

open access: yesElectronic Journal of Differential Equations, 2014
We prove an existence result for a "generalized" Monge-Ampere equation, introduced in [11], under some assumptions on a flat complex 3-torus. As an application we prove the existence of Chern connections on certain kinds of holomorphic vector bundles ...

Shaping Single Offset Reflector Antennas Using Local Axis-Displaced Confocal Quadrics

open access: yesInternational Journal of Antennas and Propagation, 2016
This work investigates a novel numerical procedure for the solution of an exact formulation for the Geometrical Optics synthesis of a single reflector antenna by simultaneously imposing Snell’s Law and Conservation of Energy in a tube of rays, yielding a

Dirichlet problem for degenerate elliptic complex Monge-Ampere equation

open access: yesElectronic Journal of Differential Equations, 2004
We consider the Dirichlet problem $$ det ig({frac{partial^2u}{partial z_ipartial overline{z_j}}} ig)=g(z,u)quadmbox{in }Omega,, quad uig|_{ partial Omega }=varphi,, $$ where $Omega$ is a bounded open set of $mathbb{C}^{n}$ with regular boundary, $g$ and $

Symmetries, Reductions and Exact Solutions of Nonstationary Monge–Ampère Type Equations

open access: yesMathematics
A family of strongly nonlinear nonstationary equations of mathematical physics with three independent variables is investigated, which contain an arbitrary degree of the first derivative with respect to time and a quadratic combination of second ...

Monotone and Consistent discretization of the Monge-Ampere operator

open access: yes, 2014
We introduce a novel discretization of the Monge-Ampere operator, simultaneously consistent and degenerate elliptic, hence accurate and robust in applications.
