Abstract: | We prove that every homomorphism \(\mathcal{O}^{E}_{\zeta}\rightarrow\mathcal{O}^{F}_{\zeta}\), with E and F Banach spaces and ζ∈? m , is induced by a \(\mathop{\mathrm{Hom}}(E,F)\)-valued holomorphic germ, provided that 1≤m<∞. A similar structure theorem is obtained for the homomorphisms of type \(\mathcal{O}^{E}_{\zeta}\rightarrow\mathcal{S}_{\zeta}\), where \(\mathcal{S}_{\zeta}\) is a stalk of a coherent sheaf of positive depth. We later extend these results to sheaf homomorphisms, obtaining a condition on coherent sheaves which guarantees the sheaf to be equipped with a unique analytic structure in the sense of Lempert–Patyi. |
