Diagonal cubic equations
in four variables with prime coefficients
joint with C.L. Basile
We give an alternative proof of a theorem
of R. Heath-Brown regarding the existence of non-zero integral solutions
of the equation p1X13 + p2X23 + p3X33 + p4X43 = 0, where the pj are
prime integers = 2 (mod 3).
