@phdthesis{16340, author = {Johannes Haubner}, title = {Shape Optimization for Fluid-Structure Interaction}, abstract = {In this thesis, shape optimization for unsteady fluid-structure interaction problems via the method of mappings is investigated theoretically and numerically. New existence and regularity results are proven. A framework for deriving differentiability for the solution of nonlinear, unsteady, parameter-dependent partial differential equations is developed and applied to show differentiability of the states with respect to domain variations.}, year = {2020}, journal = {Technical University of Munich}, url = {https://mediatum.ub.tum.de/doc/1520895/file.pdf}, }
