SUMMARY:On some variational problems and L1-estimates - Bogdan Raita (Univ
 ersity of Oxford)

DESCRIPTION:We review some recent work on the analysis of linear elliptic 
 systems with L1-data. Such estimates contrast classical Calderón-Zygmund 
 theory by Ornstein's non-inequality. Surprising weaker estimates in full-s
 pace were proved relatively recently by Bourgain\, Brezis\, and Van Schaft
 ingen\, under new conditions specific to the L1-case. We provide the analo
 gous results on domains\, which require strictly stronger conditions.\n
