On the continuity of solutions to advection-diffusion equations with slightly super-critical divergence-free drifts

open access: yesAdvances in Nonlinear Analysis, 2014
We address the regularity of solutions to elliptic and parabolic equations of the form -Δu+b·∇u=0${- \Delta u+b\cdot \nabla u=0}$ and ut-Δu+b·∇u=0${u_t- \Delta u+b\cdot \nabla u=0}$ with divergence-free drifts b.

Boundedness and monotonicity of principal eigenvalues for boundary value problems with indefinite weight functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 1, Page 25-29, 2002., 2002
We study the principal eigenvalues (i.e., eigenvalues corresponding to positive eigenfunctions) for the boundary value problem: −Δu(x) = λg(x)u(x), x ∈ D; (∂u/∂n)(x) + αu(x) = 0, x ∈ ∂D, where Δ is the standard Laplace operator, D is a bounded domain with smooth boundary, g : D → ℝ is a smooth function which changes sign on D and α ∈ ℝ.

Continuous and Lp estimates for the complex Monge‐Ampère equation on bounded domains in ℂn

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 11, Page 705-707, 2002., 2002
Continuous solutions with continuous data and Lp solutions with Lp data are obtained for the complex Monge‐Ampère equation on bounded domains, without requiring any smoothness of the domains.

Strong unique continuation of eigenfunctions for p‐Laplacian operator

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 3, Page 213-216, 2001., 2001
We show the strong unique continuation property of the eigenfunctions for p‐Laplacian operator in the case p < N.

Existence of four solutions for the elliptic problem with nonlinearity crossing one eigenvalue

open access: yesJournal of Inequalities and Applications, 2013
We investigate the multiplicity of the weak solutions for the nonlinear elliptic boundary value problem. We get a theorem which shows the existence of at least four weak solutions for the asymptotically linear elliptic problem with Dirichlet boundary ...

Locality properties of standard homogenization commutator [PDF]

open access: yesarXiv, 2021
In the present work we study how the standard homogenization commutator, a random field that plays a central role in the theory of fluctuations, quantitatively decorrelates on large scales.

Strong unique continuation for general elliptic equations in 2D [PDF]

open access: yesJ. Math. Anal. App. 386 (2012) 669--676, 2010
We prove that solutions to elliptic equations in two variables in divergence form, possibly non-selfadjoint and with lower order terms, satisfy the strong unique continuation property.

A duality theorem for solutions of elliptic equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 1, Page 73-85, 1990., 1990
Let L be a second order linear partial differential operator of elliptic type on a domain Ω of ℝm with coefficients in C∞(Ω). We consider the linear space of all solutions of the equation Lu = 0 on Ω with the topology of uniform convergence on compact subsets and describe the topological dual of this space. It turns out that this dual may be identified

Regularity properties of optimal transportation problems arising in hedonic pricing models [PDF]

open access: yes, 2011
We study a form of optimal transportation surplus functions which arise in hedonic pricing models. We derive a formula for the Ma-Trudinger-Wang curvature of these functions, yielding necessary and sufficient conditions for them to satisfy (A3w).
