AbstractGiven an integralm-currentT0 in ℝm+k and a tensorH of typ (m, 1) on ℝm+k with values orthogonal to each of its arguments we prove the existence of an integralm-currentT with boundary ∂T=∂T0 having prescribed mean curvature vectorH, i. e.
$$T = \underline{\underline \tau } (M,\theta ,\xi )$$
is a solution of for all vectorfieldsX: ℝm+k → ℝm+k with spt(X)∩spt(∂T)=Ø. It turns out that we can solve the above equation assuming
$$\left| H \right|< \gamma _m^{ - 1} 2^{ - 1/m} m(m + 1)^{ - 1 - 1/m} M(\tilde T)^{ - 1/m} ,$$
where γm denotes the constant of Almgren’s Isoperimetric Theorem and
$$\tilde T$$
is an integralm-current minimizing mass for the boundary ∂T0.
