It is proved that if T-i are linear continuous operators then the following
(algebraically) exact complex:
[GRAPHICS]
splits for i greater than or equal to 1, i.e., T-i : (D'(Omega(i)))(Si) -->
Im T-i has a continuous and linear right inverse. If T-0 is a matrix of co
nvolution operators, then the complex (*) splits for i = 0 if and only if F
is a strict projective limit of LB-spaces.
