Let be a Banach function algebra on a compact space , and let be such that for any scalar the element is not a divisor of zero. We show that any complete norm topology on that makes the multiplication by continuous is automatically equivalent to the original norm topology of . Related results for general Banach spaces are also discussed.

We consider harmonic semi-conformal maps between two Riemannian manifolds. By deforming conformally the codomain metric, we construct new examples of non-harmonic biharmonic maps. 相似文献

The paper establishes a necessary and sufficient condition under which a lacunary series belong to a mixed norm space of functions
holomorphic in the unit disc. As a corollary, some sharp pointwise estimates are obtained for lacunary series. 相似文献

Archiv der Mathematik - It is well known that the Korenblum maximum principle holds in Bergman spaces $$mathrm {A}^{p}$$ if and only if $$pge 1$$ . In this note, we improve this result by proving... 相似文献
