Noncommutative Reduction of Nonlinear Schrödinger Equation on Lie Groups
Universe, 2022 We propose a new approach that allows one to reduce nonlinear equations on Lie groups to equations with a fewer number of independent variables for finding particular solutions of the nonlinear equations.

Nonautonomous Nonlinear Scalar Field Equations in R2
Journal of Differential Equations, 1993 The authors get one positive and infinitely many radially symmetric solutions for a class of nonautonomous nonlinear scalar field equations in \(\mathbb{R}^ 2\). They use the Mountain Pass Lemma and the known method to approximate equations with strong nonlinear terms.

An estimation from within of the reachable set of nonlinear R. Brockett integrator with small nonlinearity [PDF]
Yugoslav Journal of Operations Research, 2013 In this paper, the nonlinear R. Brockett integrator with small nonlinear addition to the right-hand side of the corresponding differential equations is considered. More precisely, investigating the possibility to estimate from within the corresponding

A supersolution-subsolution method for nonlinear biharmonic equations in $$\mathbb{R}^N $$ [PDF]
Czechoslovak Mathematical Journal, 1997 This paper provides a refined version of the supersolution-subsolution method which applies to the nonlinear biharmonic equation \[ \Delta ({| \Delta u| }^{p-2} \Delta u) = f(x,u), \qquad x \in \mathbb R^N \] where \(p>1\), \(N \geq 3\) and \(f\in C^{\alpha }_{\text{loc}} (\mathbb R^N \times \mathbb R_+)\) for some \(\alpha \in (0,1)\), \(\mathbb R_+ =

On a fractional nonlinear equation on a bounded domain of $\mathbb R^n$
Rendiconti del Seminario Matematico della Università di Padova, 2019 We establish perturbation results for a Nirenberg type equation involving the fractional Laplacian on a bounded domain of \mathbb R^n, n \geq 2 . Our method is based on the critical points at infinity theory of [6].

On 2D Nonlinear Schrödinger Equations with Data on R×T
Journal of Functional Analysis, 2001 AbstractWe prove L2 global well-posedness results for 2D (subcritical and critical) nonlinear Schrödinger equations with data on R×T. We use methods of the periodic case due to J. Bourgain. The main ingredient in the proof is the L4−L2 Strichartz inequality for the free evolution which fails in the purely periodic setting.
