Stability of abstract thermoelastic delayed systems

In this talk, a stabilization problem for a generalized thermoelastic system with delay, known as the $\alpha-\beta$ system, is addressed. The well-posedness of the system is proven using the semigroup approach. Under certain conditions, exponential and polynomial stability of the system is established via a frequency-domain approach. These theoretical results are then applied to specific examples in thermoelasticity.

Asymtotic behavior of positive solutions for a degenerate logistic equation with mixed local and non-local diffusion

In this work, we analyze a stationary degenerate logistic equation with both local and non-local diffusion. Primarily employing bifurcation results, sub- and supersolution methods, and maximum principles, we establish results regarding the existence, non-existence, and uniqueness of positive solutions. Additionally, using appropriate large solutions, we conduct a detailed study of the asymptotic behavior of the solutions with respect to one of the equation’s parameters, showing that the presence of the non-local diffusion can drastically change this point-wise behavior when compared with the local case
