Title: Flagellar Wrapping in Swimming Bacteria

Abstract:
Flagellated bacteria swim in fluids by rotating flagella driven by molecular motors. Understanding how these cells reorient and navigate is essential for interpreting mechanisms relevant to environmental adaptation, symbiosis, and pathogenesis. Yet, the hydrodynamics of these microswimmers are complex, making quantitative insight challenging from experiments alone. In this talk, we introduce a versatile mathematical model of a self-propelled microswimmer. By integrating our modeling with experimental observations of microswimmers exhibiting flagellar wrapping, we characterize the hydrodynamic mechanisms underlying their complex swimming behaviors.

Title: Existence of weak solutions for p-Laplace type equations

Abstract: Equations of a class of nonlinear p-Laplace will be discussed by the variational method for infinitely many solutions.
