Quasiminimal sets are sets whose Hausdorff measure cannot be reduced beyond a certain percentage through deformation. This notion, introduced by David and Semmes, models soap films minimizing highly irregular energies, but also fracture without deformation in inhomogeneous solids. In this talk, I will present a joint work with Yana Teplitskaya to determine their optimal regularity in low dimension. This projet is motivated by the work of David and collaborators, who dealt with the case where a quasiminimal set only separates a finite number of components.
