Geophysical Monge–Ampère-Type Equation: Symmetries and Exact Solutions
MathematicsThis paper studies a mixed PDE containing the second time derivative and a quadratic nonlinearity of the Monge–Ampère type in two spatial variables, which is encountered in geophysical fluid dynamics.

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

A fully nonlinear generalized Monge-Ampere PDE on a torus
Electronic 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
International 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
Electronic 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 $
