On symmetry reduction and some classes of invariant solutions of the (1+3)-dimensional homogeneous Monge-Ampère equation

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2021
We study the relationship between structural properties of the two-dimensional nonconjugate subalgebras of the same rank of the Lie algebra of the Poincaré group P(1,4) and the properties of reduced equations for the (1+3)-dimensional homogeneous Monge ...

Lp‐Curvature Measures and Lp,q‐Mixed Volumes

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
Motivated by Lutwak et al.’s Lp‐dual curvature measures, we introduce the concept of Lp‐curvature measures. This new Lp‐curvature measure is an extension of the classical surface area measure, Lp‐surface area measure, and curvature measure. In this paper, we first prove some properties of the Lp‐curvature measure.

New Results on the Radial Solutions to a Class of Nonlinear k‐Hessian System

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
This paper investigates the positive radial solutions of a nonlinear k‐Hessian system. ΛSk1/kλD2z1Sk1/kλD2z1=bxφz1,z2, x∈ℝNΛSk1/kλD2z2Sk1/kλD2z2=hxψz1,z2, x∈ℝN, where Λ is a nonlinear operator and b, h, φ, ψ are continuous functions. With the help of Keller–Osserman type conditions and monotone iterative technique, the positive radial solutions of the ...

Newton Linearization of the Curvature Operator in Structured Grid Generation with Sample Solutions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2022, Issue 1, 2022., 2022
Elliptic grid generation equations based on the Laplacian operator have the well‐known property of clustering the mesh near convex boundaries and declustering it near concave boundaries. In prior work, a new differential operator was derived and presented to address this issue.

The Initial and Neumann Boundary Value Problem for a Class Parabolic Monge-Ampère Equation

open access: yesAbstract and Applied Analysis, 2013
We consider the existence, uniqueness, and asymptotic behavior of a classical solution to the initial and Neumann boundary value problem for a class nonlinear parabolic equation of Monge-Ampère type. We show that such solution exists for all times and is

Real Monge-Ampere equations and Kahler-Ricci solitons on toric log Fano varieties [PDF]

open access: yes, 2012
We show, using a direct variational approach, that the second boundary value problem for the Monge-Amp\`ere equation in R^n with exponential non-linearity and target a convex body P is solvable iff 0 is the barycenter of P.

Minimal convex extensions and finite difference discretization of the quadratic Monge-Kantorovich problem [PDF]

open access: yes, 2018
We present an adaptation of the MA-LBR scheme to the Monge-Amp{\`e}re equation with second boundary value condition, provided the target is a convex set.
