Abstract:
For vector valued maps, convergence in $W^{1,1}$ and of all minors of the Jacobian matrix in $L^{1}$ is equivalent to convergence weakly in the sense of currents and in area for graphs. We show that maps defined on domains of dimension $n\geq 3$ can be approximated strongly in this sense by smooth maps if and only if the same property holds for the restriction to a.e. $2$-dimensional plane intersecting the domain.
