DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/38/">Pa
 thological Sobolev homeomorphisms in GFT and NE</a>\nby Daniel Campbell (U
 niversity of Hradec Kralove) as part of Online Seminar "Geometric Analysis
 "\n\n\nAbstract\nSobolev homeomorphisms are the natural choice for minimiz
 ation problems in non-linear elasticity. For the regularity of these probl
 ems it would be useful to be able to approximate these maps by smooth home
 omorphisms in their corresponding Sobolev space (the so-called Ball-Evans 
 problem). We construct a pair of homeomorphisms for which is impossible si
 multaneously solving the Hajlasz problem. That is we construct a Sobolev h
 omeomorphism equalling identity on the boundary of a cube but with negativ
 e Jacobian almost everywhere.\n
