Analyticité partielle et suites d’unicité. (Partial analyticity and uniqueness sequences). (French) Zbl 0762.32002
The author introduces two kinds of uniqueness sequences $$(z_ k)$$, weak and strong, for a family of mappings $$\rho=(\rho_ \varepsilon)$$, $$\varepsilon=(\varepsilon_ 1,\dots,\varepsilon_ n)$$ being positive parameters, which describes the density of this sequence. Employing this, he generalizes the uniqueness theorem for holomorphic functions in the form that if $$(z_ k)$$ is a weak uniqueness sequence, $$f^{(k)}(z_ k)=0$$ for all $$k$$ implies $$f\equiv 0$$. He also gives an analogy of this uniqueness theorem for hyperfunctions with compact support containing real analytic parameters $$t$$ with respect to a strong uniqueness sequence $$(t_ k)$$. Some open problems for the case of distributions with real analytic parameters but without restriction of support are discussed. These may be progressed in view of a recent result of J. Boman [C. R. Acad. Sci., Paris, Sér. I 315, 1231-1234 (1992)].
