Quasilinear theory of high-gain FEL saturation [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2001 Abstract Understanding of saturation behavior is important to assess the performance of a high-gain free-electron laser. In this paper, we study the saturation mechanism using a quasilinear approximation to the coupled Maxwell–Vlasov equations. It is found that the quasilinear theory correctly describes the evolution of the radiation field from the ...

Experimental and Numerical Investigation of Stress Waves in Soil Under Shallow Explosions
Shock and Vibration, Volume 2026, Issue 1, 2026.The propagation characteristics of stress waves in soil directly influence the safety assessment of underground structures, engineering protection design, and disaster prediction. When explosives are detonated at different burial depths, the shallow underground medium near the explosion center will be simultaneously subjected to direct ground shock and

Local Regularity For Elliptic Systems With p, q-Growth
Bruno Pini Mathematical Analysis Seminar, 2015 In this paper we consider quasilinear elliptic systems with p, q-growth. We discuss some aspects of the theory of regularity for systems and we state a local boundedness result for weak solutions, obtained in collaboration with P. Marcellini. Moreover, a

Chaos and unpredictability with time inconsistent policy makers
Theoretical Economics, Volume 21, Issue 1, Page 241-280, January 2026.We analyze the existence of equilibria with complex dynamics in a policy framework with time inconsistency. We consider an economy where, in each period, the policy maker in power determines the level of a durable public good (or bad) that creates strategic linkages across policy periods. When the decision‐making process is time consistent—such as when

The Existence and Behavior of Solutions for Nonlocal Boundary Problems
Boundary Value Problems, 2009 The purpose of this work is to investigate the uniqueness and existence of local solutions for the boundary value problem of a quasilinear parabolic equation. The result is obtained via the abstract theory of maximal regularity. Applications are given to

A Fredholm alternative for quasilinear elliptic equations with right-hand side measure
Advances in Nonlinear Analysis, 2016 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. For this purpose we develop a variant of degree theory

Engineering Reports, Volume 7, Issue 12, December 2025.Bio‐inspired PLA‐hemp sandwich cores with honeycomb and lotus root geometries were 3D printed and tested. Lotus designs showed superior damping and stable dynamic response, while honeycomb cores offered higher stiffness. Simulations matched experiments closely. ABSTRACT This study investigates the elastic behavior and dynamic mechanical response of bio‐

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

Existence of solutions for quasilinear elliptic systems involving critical exponents and Hardy terms
Electronic Journal of Differential Equations, 2013 Using variational methods, including the Ljusternik-Schnirelmann theory, we prove the existence of solutions for quasilinear elliptic systems with critical Sobolev exponents and Hardy terms.
