Ground State Solutions of Schrödinger‐Kirchhoff Equations with Potentials Vanishing at Infinity

Journal of Function Spaces, Volume 2023, Issue 1, 2023., 2023
In this paper, we deal with the following Schrödinger‐Kirchhoff equation with potentials vanishing at infinity: −ε2a+εb∫ℝ3∇u2Δu+Vxu=Kxup−1u in ℝ3and u > 0, u ∈ H1(ℝ3), where V(x) ~ |x|−α and K(x) ~ |x|−β with 0 < α < 2, and β > 0. We first prove the existence of positive ground state solutions uε ∈ H1(ℝ3) under the assumption that σ < p < 5 for some σ =

Parametric superlinear double phase problems with singular term and critical growth on the boundary

Mathematical Methods in the Applied Sciences, Volume 45, Issue 4, Page 2276-2298, 15 March 2022., 2022
In this paper, we study quasilinear elliptic equations driven by the double phase operator along with a reaction that has a singular and a parametric superlinear term and with a nonlinear Neumann boundary condition of critical growth. Based on a new equivalent norm for Musielak–Orlicz Sobolev spaces and the Nehari manifold along with the fibering ...

Majorization Properties for Certain Subclasses of Meromorphic Function of Complex Order

Complexity, Volume 2022, Issue 1, 2022., 2022
By making use of q−differential operators, many distinct subclasses of analytic and meromorphic functions have already been defined and investigated from numerous perspectives. In this article, we investigated several majorization results for the class of meromorphic univalent functions of complex order, defined by q−differential operator. Moreover, we

A geometrical view of the Nehari manifold [PDF]

Methods and Applications of Analysis, 2012
We study the Nehari manifold N associated to the boundary value problem −∆u = f(u) , u ∈ H 0 (Ω) , where Ω is a bounded regular domain in Rn. Using elementary tools from Differential Geometry, we provide a local description of N as an hypersurface of the Sobolev space H1 0 (Ω). We prove that, at any point u ∈ N , there exists an exterior tangent sphere

Bilateral Harnack Inequalities for Stochastic Differential Equation with Multiplicative Noise

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
By constructing a coupling with unbounded time‐dependent drift, a lower bound estimate of dimension‐free Harnack inequality with power is obtained for a large class of stochastic differential equation with multiplicative noise. The key is an application of the inverse Hölder inequality.

Ground State Solution for a Fourth Order Elliptic Equation of Kirchhoff Type with Critical Growth in ℝN

Advances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022
In this paper, we consider the following fourth order elliptic Kirchhoff‐type equation involving the critical growth of the form Δ2u−a+b∫ℝN∇u2dxΔu+Vxu=Iα∗Fufu+λu2∗∗−2u,in ℝN,u∈H2ℝN, where a > 0, b ≥ 0, λ is a positive parameter, α ∈ (N − 2, N), 5 ≤ N ≤ 8, V : ℝN⟶ℝ is a potential function, and Iα is a Riesz potential of order α.

Existence and asymptotic behaviour of positive ground state solution for critical Schrödinger-Bopp-Podolsky system

Electronic Research Archive, 2022
In this paper, we consider a class of critical Schrödinger-Bopp-Podolsky system. By virtue of the Nehari manifold and variational methods, we study the existence, nonexistence and asymptotic behavior of ground state solutions for this problem.

On p(z)–Laplacian System Involving Critical Nonlinearities

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this paper, we deal with the existence of at least two nonnegative nontrivial solutions to a p(z)–Laplacian system involving critical nonlinearity in the context of Sobolev spaces with variable exponents on complete manifolds. We have established our main results by exploring both Nehari’s method and doing a refined analysis on the associated fiber ...
