PhD Colloquia

June 23, 2022 – HS15, Oskar-Morgenstern-Platz 1 & online (BBB at the following link)
1.15 pm: PhD Colloquium – Katharina Brazda: Biomembranes, curves, and varifolds

The equilibrium configurations of biological membranes, like the famous biconcave shapes of human red blood cells, can be modeled by minimizing the Canham-Helfrich elastic bending energy. In this talk, I will first introduce this quadratic curvature functional as well as its generalization to heterogeneous biomembranes, where shape couples to composition. Then I will discuss the 1D counterpart of the Canham-Helfrich model, namely elastic curves with modulated stiffness. Coming back to multiphase membranes, I will finally give you an idea about how the variational problem can be addressed with concepts of geometric measure theory, in particular, curvature varifolds.
You can find the poster here.
