The hypersurfaces with conformal normal Gauss map in Hn+1 and S1n+1
In this paper, we introduce the fourth fundamental forms for hypersurfaces in Hn+1 and space-like hypersurfaces in S1n+1, and discuss the conformality of the normal Gauss map of the hypersurfaces in Hn+1 and S1n+1.

Geophysical Monge–Ampère-Type Equation: Symmetries and Exact Solutions
This 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
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

Finite element approximations of the three dimensional Monge-Ampère equation [PDF]
In this paper, we construct and analyze finite element methods for the three dimensional Monge-Ampère equation. We derive methods using the Lagrange finite element space such that the resulting discrete linearizations are symmetric ...

A fully nonlinear generalized Monge-Ampere PDE on a torus
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
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

Convergence Rate of a Stable, Monotone and Consistent Scheme for the Monge-Ampère Equation
We prove a rate of convergence for smooth solutions of the Monge-Ampère equation of a stable, monotone and consistent discretization. We consider the Monge-Ampère equation with a small low order perturbation.

On the integrability of a class of Monge-Ampère equations [PDF]
We give the Lax representations for the elliptic, hyperbolic and homogeneous second order Monge-Ampère equations. The connection between these equations and the equations of hydrodynamical type give us a scalar dispersionless Lax representation. A matrix
