The Dominant Role of the Electron Isotropy Boundary in Controlling Earth's Outer Radiation Belt Electron Lifetimes

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Field‐line curvature scattering (FLCS) is believed to be the primary mechanism forming electron isotropy boundaries (IB) and can rapidly scatter relativistic electrons from the outer radiation belt. However, its direct and quantitative impact on controlling outer belt electron lifetimes has never been directly assessed.

Existence of a renormalized solution to a nonlinear elliptic equation with L1-data in the space Rn

open access: yesСовременная математика: Фундаментальные направления
We consider a second-order quasilinear elliptic equation with an integrable right-hand side in the space Rn. Restrictions on the structure of the equation are formulated in terms of a generalized N -function.

Existence of minimal and maximal solutions for a quasilinear elliptic equation with integral boundary conditions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This work is concerned with the construction of the minimal and maximal solutions for a quasilinear elliptic equation with integral boundary conditions, where the nonlinearity is a continuous function depending on the first derivative of the unknown ...

Dimer models and conformal structures

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.
Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

Dirichlet problems for semilinear elliptic equations with a fast growth coefficient on unbounded domains

open access: yesElectronic Journal of Differential Equations, 2005
When an unbounded domain is inside a slab, existence of a positive solution is proved for the Dirichlet problem of a class of semilinear elliptic equations that are similar either to the singular Emden-Fowler equation or a sublinear elliptic equation ...

Multiplicity of Solutions to a Potential Operator Equation and Its Applications

open access: yesAbstract and Applied Analysis, 2014
We consider the multiplicity of solutions for operator equation involving homogeneous potential operators. With the help of Nehari manifold and fibering maps, we prove that such equation has at least two nontrivial solutions.

Solutions to p(x)-Laplace type equations via nonvariational techniques [PDF]

open access: yesOpuscula Mathematica, 2018
In this article, we consider a class of nonlinear Dirichlet problems driven by a Leray-Lions type operator with variable exponent. The main result establishes an existence property by means of nonvariational arguments, that is, nonlinear monotone ...

On the principle of linearized stability for quasilinear evolution equations in time‐weighted spaces

open access: yesMathematische Nachrichten, Volume 298, Issue 12, Page 3939-3959, December 2025.
Abstract Quasilinear (and semilinear) parabolic problems of the form v′=A(v)v+f(v)$v^{\prime }=A(v)v+f(v)$ with strict inclusion dom(f)⊊dom(A)$\mathrm{dom}(f)\subsetneq \mathrm{dom}(A)$ of the domains of the function v↦f(v)$v\mapsto f(v)$ and the quasilinear part v↦A(v)$v\mapsto A(v)$ are considered in the framework of time‐weighted function spaces ...

Three solutions for quasilinear equations in Rn near resonance

open access: yesElectronic Journal of Differential Equations, 2001
We use minimax methods to prove the existence of at least three solutions for a quasilinear elliptic equation in $mathbb {R}^n$ near resonance.
