A Fredholm alternative for quasilinear elliptic equations with right hand side measure
, 2015 We consider a quasilinear elliptic equation, with right hand side measure, which does not satisfy the usual coercivity assumption. We prove an existence result in the line of the Fredholm alternative.

Journal of Sensors, Volume 2025, Issue 1, 2025.Liquid level measurement (LLM) systems are extensively used in industry. Although most liquid measurement systems are based on indirect measurement, flow‐based monitoring is the most used secondary measuring technique for LLM. A comprehensive review of the existing LLM techniques including optical, image‐based, capacitive, and float sensors is ...

Journal of Geophysical Research: Space Physics, Volume 129, Issue 12, December 2024.Abstract Whistler mode waves scatter energetic electrons, causing them to precipitate into the Earth's atmosphere. While the interactions between whistler mode waves and electrons are well understood, the global distribution of electron precipitation driven by whistler mode waves needs futher investigations.

Proton Cyclotron Waves and Pickup Ion Ring Distribution Instabilities Upstream of Mars
Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.Abstract Proton cyclotron waves (PCWs) upstream of Mars are thought to be associated with the instabilities of pickup ions. The instabilities of pickup ions of ring distributions have larger maximum growth rates compared with beam distributions.

Solutions to singular quasilinear elliptic equations on bounded domains
Electronic Journal of Differential Equations, 2018 In this article we study quasilinear elliptic equations with a singular operator and at critical Sobolev growth. We prove the existence of positive solutions.

Positive solutions of quasilinear elliptic equations
Topological Methods in Nonlinear Analysis, 1998 (1.2) { −∆pu = λa(x)|u|p−2u, u ∈ D 0 (Ω), has the least eigenvalue λ1 > 0 with a positive eigenfunction e1 and λ1 is the only eigenvalue having this property (cf. Proposition 3.1). This gives us a possibility to study the existence of an unbounded branch of positive solutions bifurcating from (λ1, 0).
