Special Issue Information

Dear Colleagues,

Partial differential equations (PDEs) serve as the cornerstone for modeling a myriad of phenomena in physics, engineering, biology, and finance. Among the plethora of PDE-related studies, stability analysis occupies a pivotal position due to its profound implications in understanding the long-term behavior of solutions and designing control strategies. This Special Issue is dedicated to exploring the latest advancements in the stability theory of partial differential equations, with a particular focus on the following topics:

  1. Stability analysis of nonlinear PDEs: Papers exploring various stability criteria for different classes of nonlinear PDEs are welcome. Both theoretical investigations and applications to real-world problems are encouraged.
  2. Stabilization problems in linear or nonlinear PDEs: Papers addressing the challenge of designing feedback mechanisms or control laws to stabilize linear or nonlinear PDE systems around equilibrium points or desired trajectories are highly sought after. Contributions may include novel control techniques, numerical simulations, and experimental validations.
  3. Interdisciplinary applications: We encourage submissions that demonstrate how stability theory can be applied to solve practical problems across diverse disciplines, such as fluid dynamics, electrical engineering, material science, ecological modeling, financial mathematics, etc.

Authors are invited to submit original research articles or review papers that fall within the scope of this Special Issue. Submissions should adhere to the standard formatting guidelines of the journal and emphasize clarity, rigor, and relevance to the theme of PDE stability. All manuscripts will undergo a thorough peer review process to ensure scientific excellence and quality.

We look forward to receiving your valuable contributions and working together to advance our understanding of the stability and stabilization in PDEs.

In this work, we investigate the stability of solutions in a situation where the logarithmic source term competes with the viscoelastic dissipation under acoustic boundary conditions. We assume minimal conditions on the relaxation function g, namely, g(t)ξ(t)H(g(t)), where H is a strictly increasing and strictly convex function near the origin, and ξ(t) is a non-increasing function. Under these general assumptions, we establish a general decay estimate for the solution. This result extends and improves some previous results. Full article
