We give conditions for a vector-valued function u โ W 1,n (โฆ, R n ), satisfying det Du(x) 0 on a bounded domain โฆ, which imply that det Du(x) is globally higher integrable on โฆ. We also give conditions for u โ W 1,n (โฆ, R n ) such that det Du belongs to the Hardy space h 1 z (โฆ) and exhibit some exa
