DESCRIPTION:Speakers: Tokuhiro Eto (ICJ - Lyon 1)\n\nWe present a unified 
 structure-preserving finite element framework for multi-phase Mullins–Se
 kerka type problems with triple junctions. Starting from the isotropic for
 mulation\, which ensures exact volume conservation and unconditional energ
 y stability\, we progressively extend the model to incorporate anisotropic
  surface energies\, variable mobility\, and kinetic undercooling. The prop
 osed discretization preserves the energy-dissipating structure of the cont
 inuous problem\, providing a robust and physically consistent numerical sc
 heme. Through numerical experiments\, we demonstrate complex interfacial d
 ynamics of evolving networks and illustrate how anisotropy and kinetic eff
 ects influence the morphology and stability of the system. This talk is b
 ased on joint works with Harald Garcke (Universität Regensburg\, Germany)
  and Robert Nürnberg (Università di Trento\, Italy).\n\nhttps://indico.m
