Abstract :
Let R = k[x1; x2... ; xN] be a polynomial ring over
a field k. We prove that for any positive integers m; n,
reg(ImJnK) mreg(I) + nreg(J) + reg(K).if I; J;K R are three monomial complete intersections (I, J, K
are not necessarily proper ideals of the polynomial ring R), and
I; J are of the form
