In the work we consider a topological module of entire functions, which is the isomorphic image under the Fourier-Laplace transform of Schwarz space ℰ ′ of distributions compactly supported in a finite or infinite interval ( ; ) ⊂ R. We study some properties of closed submodules in module related with local description problem. We also study issues on duality between closed submodules in and subspaces in the space ℰ = ∞ ( ; ) invariant w.r.t. the differentiation.
