Long-time behavior for the Kirchhoff diffusion problem with magnetic fractional Laplace operator
Jiabin Zuo, Juliana Honda Lopes, Vicentiu D. Rădulescu
We consider a Kirchhoff-type diffusion problem driven by the magnetic fractional Laplace operator. The main result in this paper establishes that infinite time blow-up cannot occur…
Convergence of least energy sign-changing solutions for logarithmic Schrödinger equations on locally finite graphs
Xiaojun Chang, Vicenţiu D. Rădulescu, Ru Wang +1
In this paper, we study the following logarithmic Schrödinger equation \[ -Δu+λa(x)u=u\log u^2\ \ \ \ \mbox{ in }V \] on a connected locally finite graph , where denot…
Discovery and physical characterization as the first response to a potential asteroid collision: The case of 2023 DZ2
Marcel M. Popescu, O. Văduvescu, Julia de León +15
Near-Earth asteroids (NEAs) that may evolve into impactors deserve detailed threat assessment studies. Early physical characterization of a would-be impactor may help in optimizing…
Global multiplicity for parametric anisotropic Neumann -equations
Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš
We consider a Neumann boundary value problem driven by the anisotropic -Laplacian plus a parametric potential term. The reaction is ``superlinear". We prove a global (with r…
The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics
C. M. Raiteri, M. Villata, S. G. Jorstad +13
In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…
Quantitative estimates of convergence in nonlinear operator extensions of Korovkin's theorems
Sorin G. Gal, Constantin P. Niculescu
This paper is aimed to prove a quantitative estimate (in terms of the modulus of continuity) for the convergence in the nonlinear version of Korovkin's theorem for sequences of wea…
