D. Mucci, GRAPHS OF FINITE MASS WHICH CANNOT BE APPROXIMATED BY SMOOTH GRAPHS WITH EQUIBOUNDED AREA, Journal of functional analysis, 152(2), 1998, pp. 467-480
We show that there exist graphs of Cartesian maps, of finite mass, whi
ch cannot be approximated weakly as currents by graphs of smooth maps
with equibounded area. (C) 1998 Academic Press.
