Let E be a quasi-complete
dual nuclear complex locally convex space; we prove that both spaces ℋNb(E) and
ℋSNb(E) of entire functions of nuclear type on E introduced by Matos and
Matos-Nachbin coincide with the space ℋS(E) of the Silva holomorphic functions. As
a consequence, well known results of Boland on convolution equations in
ℋ(E) can be obtained as particular cases of results in Matos’s Doctoral
Dissertation.
