DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NCTS-GMT/9/"
 >A regularity theorem for area-minimizing currents at higher multiplicity 
 boundary points</a>\nby Simone Steinbrüchel (Leipzig University) as part 
 of NCTS international Geometric Measure Theory seminar\n\n\nAbstract\nThe 
 boundary regularity theory for area-minimizing integral currents in higher
  codimension has been completed in 2018 by a work of De Lellis\, De Philip
 pis\, Hirsch and Massaccesi proving the density of regular boundary points
 . In this talk\, I will present our recent paper where we took a first ste
 p into analyzing area-minimizing currents with higher multiplicity boundar
 y. This question has first been raised by Allard and later again by White.
  We focus on two-dimensional currents with a convex barrier and define the
  regular boundary points to be those around which the current consists of 
 finitely many regular submanifolds meeting transversally at the boundary. 
 Adapting the techniques of Almgren\, we proved that every boundary point i
 s regular in the above sense. This is a joint work with C. De Lellis and S
 . Nardulli.\n\nGet-together (30 min) $\\cdot$ presentation Simone Steinbr
