On the Strong Convergence of Some Optimization Algorithms in the Linear Case

Many algorithms in optimization generate a sequence that converges weakly to a solution. Under linearity assumptions, sometimes one obtains more: strong convergence and a formula for the limit. In this talk, I will report on recent work (joint with Sedi Bartz, Yuan Gao, and Walaa Moursi) on the classical KM method and some accelerated algorithms.

Qualitative Properties of Multilayered Structure-Fluid Interaction Coupled PDE Dynamics

We consider a composite structure (multilayered) and fluid interaction PDE system which arises in multi-physics problems, and particularly in biofluidic applications related to the mammalian blood transportation process. The PDE system under consideration consists of the interactive coupling of 3D Stokes flow and 3D elastic dynamics which gives rise to an additional 2D elastic equation on the boundary interface between these 3D PDE systems. We first show the existence-uniqueness properties of the coupled system by means of a nonstandard mixed variational formulation and linear semigroup theory. In the second part, we analyze the long-time behavior of the solutions to such FSI coupled system and address the issue of asymptotic decay of this solution to the zero state via a frequency domain approach.
