Quadratic Hessian Equation

open access: yes
We survey quadratic Hessian equations: definition, background, rigidity of entire solutions, regularity of viscosity solutions, a priori Hessian estimates, and open problems.

Eigenvalue problems for a k-Hessian-type equation

open access: yesNonlinear Analysis
In this work, we focus on the eigenvalue problem for a class of k-Hessian-type equations. Under some suitable assumptions, we first determine the intervals of the parameter for the existence of nontrivial radial solutions.

Global Bifurcation from Intervals for the Monge-Ampère Equations and Its Applications

open access: yesJournal of Function Spaces, 2018
We shall establish the global bifurcation results from the trivial solutions axis or from infinity for the Monge-Ampère equations: det(D2u)=λm(x)-uN+m(x)f1(x,-u,-u′,λ)+f2(x,-u,-u′,λ), in B, u(x)=0, on ∂B, where D2u=(∂2u/∂xi∂xj) is the Hessian matrix of u,

The exterior Dirichlet problem for Hessian quotient equations

open access: yes, 2012
In this paper, using a reverse MacLaurin inequality, we established the existence theorem of the exterior Dirichlet problem for Hessian quotient equations with a stronger asymptotic behavior at infinity. When k≤(n+1)/2, we improve the result in [L.M. Dai,

Comparison results for Hessian equations via symmetrization

open access: yes, 2007
In this paper, using symmetrization techniques, we prove comparison results for solutions to Hessian equations with homogeneous Dirichlet boundary conditions.

Approximating large-scale Hessian matrices using secant equations [PDF]

open access: yes
Large-scale optimization algorithms frequently require sparse Hessian matrices that are not readily available. Existing methods for approximating large sparse Hessian matrices either do not impose sparsity or are computationally prohibitive. To try and

Interior Estimates for Generalized Forchheimer Flows of Slightly Compressible Fluids

open access: yesAdvanced Nonlinear Studies, 2017
The generalized Forchheimer flows are studied for slightly compressible fluids in porous media with time-dependent Dirichlet boundary data for the pressure. No restrictions are imposed on the degree of the Forchheimer polynomial. We derive, for all time,
