Estimates for the Complex Monge-Ampère Equation on Hermitian and Balanced Manifolds [PDF]

open access: yes, 2009
We generalize Yau's estimates for the complex Monge-Ampere equation on compact manifolds in the case when the background metric is no longer Kahler. We prove $C^{\infty}$ a priori estimates for a solution of the complex Monge-Ampere equation when the ...

Partner Symmetries, Group Foliation and ASD Ricci-Flat Metrics without Killing Vectors

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We demonstrate how a combination of our recently developed methods of partner symmetries, symmetry reduction in group parameters and a new version of the group foliation method can produce noninvariant solutions of complex Monge-Ampère equation (CMA) and

Nontrivial convex solutions on a parameter of impulsive differential equation with Monge-Ampère operator

open access: yesBoundary Value Problems, 2017
The authors consider the impulsive differential equation with Monge-Ampère operator in the form of { ( ( u ′ ( t ) ) n ) ′ = λ n t n − 1 f ( − u ( t ) ) , t ∈ ( 0 , 1 ) , t ≠ t k , k = 1 , 2 , … , m , Δ ( u ′ ) n | t = t k = λ I k ( − u ( t k ) ) , k = 1

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

A Least-Squares/Relaxation Method for the Numerical Solution of the Three-Dimensional Elliptic Monge–Ampère Equation

open access: yesJournal of Scientific Computing, 2018
In this article, we address the numerical solution of the Dirichlet problem for the three-dimensional elliptic Monge–Ampère equation using a least-squares/relaxation approach.

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 $
