Let Ω be a domain in Rn, where n=2,3. Suppose that a sequence of Sobolev homeomorphisms fk:Ω→Rn with positive Jacobian determinants, J(x,fk)>0, converges weakly in W1,p(Ω,Rn), for some p⩾1, to a mapping f. We show that J(x,f)⩾0 a.e. in Ω. Generalizations to higher dimensions are also given.

Jacobian of weak limits of Sobolev homeomorphisms
Hencl, Stanislav; Onninen, Jani (Walter de Gruyter GmbH, 2018)Let Ω be a domain in Rn, where n=2,3. Suppose that a sequence of Sobolev homeomorphisms fk:Ω→Rn with positive Jacobian determinants, J(x,fk)>0, converges weakly in W1,p(Ω,Rn), for some p⩾1, to a mapping f. We show that ... 
Introducing Golden Section in the Mathematics Class to Develop Critical Thinking from the STEAM Perspective
DanaPicard, Thierry; Hershkovitz, Sara; Lavicza, Zsolt; Fenyvesi, Kristof (SEAMEO STEMED, 2021)The Golden Section is a mathematical concept that is one of the most famous examples of connections between mathematics and the arts. Despite its widespread references in various areas of nature, art, architecture, literature, ... 
Approximation of W1,p Sobolev homeomorphism by diffeomorphisms and the signs of the Jacobian
Campbell, D.; Hencl, S.; Tengvall, Ville (Elsevier Inc., 2018)Let Ω ⊂ R n, n ≥ 4, be a domain and 1 ≤ p < [n/2], where [a] stands for the integer part of a. We construct a homeomorphism f ∈ W1,p((−1, 1)n, R n) such that Jf = det Df > 0 on a set of positive measure and Jf < 0 on a set ... 
Infinitesimal Hilbertianity of Locally CAT(κ)Spaces
Di Marino, Simone; Gigli, Nicola; Pasqualetto, Enrico; Soultanis, Elefterios (Springer, 2021)We show that, given a metric space (Y,d)(Y,d) of curvature bounded from above in the sense of Alexandrov, and a positive Radon measure μμ on YY giving finite mass to bounded sets, the resulting metric measure space ... 
Aesthetics of Geometry and the Problem of Representation in Monument Sculpture
Lähdesmäki, Tuuli (Birkhäuser, 2017)Since the 1920s and 1930s, constructivist and concretist visual art movements have stressed geometric forms, proportions and orders as a base for artistic expressions and aesthetic experiences. After the World War II ...
