DESCRIPTION:Speakers: Noah Piemontese-Fischer (University of Bonn)\n\nIn t
 his talk\, we study an incompatible two-well problem that exhibits some su
 rprising flexibility properties. We consider two variants of the problem: 
 one without gauge invariance and one with SO(2) invariance. Upon taking a 
 glimpse at the relaxations of the energies\, we discuss a connection betwe
 en these variational problems and the theory of quadrature domains. This l
 ink allows us to construct minimizers with finite surface energy via tools
  from potential theory and free-boundary problems\, including partial bala
 yage\, mother bodies and a squeezing-type Hele-Shaw flow. The talk is base
 d on ongoing joint work with Lennart Machill and Angkana Rüland.\n\nhttps
