On an equation with partial derivations in four-dimensional Euclidean space

(Lobachevskii Journal of Mathematics, Volume XVIII)

The objective of this article is to construct in a hyper-rectangular region of the 4-dimensional Euclidean space a solution of the Goursat problem for the following equation:

m1 m2 m3 m4 ∑ ∑ ∑ ∑ --∂i1+i2+i3+i4u--- L (u) = ai1i2i3i4 (x1,x2,x3,x4) ∂xi1∂xi2∂xi3∂xi4 i1=0i2=0i3=0i4=0 1 2 3 4 = F (x1,x2,x3,x4) .
