DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/120/">I
 ntegral chains with coefficients in a complete normed commutative group</a
 >\nby Ulrich Menne (National Taiwan Normal University and National Center 
 for Theoretical Sciences) as part of Online Seminar "Geometric Analysis"\n
 \n\nAbstract\nAs a service to the community\, in joint work with Christian
  Scharrer\, we provide—for Euclidean space—a basic treatment of locall
 y rectifiable chains and of the complex of locally integral chains. In thi
 s setting\, we may beneficially develop the idea of a complete normed comm
 utative group bundle over the Grassmann manifold whose fibre is the coeffi
 cient group of the chains. Our exposition also sheds new light on some alg
 ebraic aspects of the theory. Finally\, we indicate an extension to a geom
 etric approach to locally flat chains centring on locally rectifiable chai
 ns rather than completion procedures.\n\nThe virtual whiteboard <a href="h
