Matricial Topological Ranks for Two Algebras of Bounded Holomorphic Functions
— Let N and D be two matrices over the algebra H∞ of bounded analytic functions in the disk, or its real counterpart H∞ R . Suppose that N and D have the same number n of columns. In a generalisation of the notion of topological stable rank 2, it is shown that N and D can be approximated (in the operator norm) by two matrices e N and e D, so that the Aryabhatta-Bezout equation X e N + Y e D = I...
متن کاملBounded Holomorphic Functions on Bounded Symmetric Domains
Let D be a bounded homogeneous domain in C , and let A denote the open unit disk. If z e D and /: D —► A is holomorphic, then ß/(z) is defined as the maximum ratio \Vz(f)x\/Hz(x, 3c)1/2 , where x is a nonzero vector in C and Hz is the Bergman metric on D . The number ßf(z) represents the maximum dilation of / at z . The set consisting of all ß/(z), for z e D and /: D —► A holomorphic, is known ...
متن کاملWeak Topologies on the Bounded Holomorphic Functions
Let G be a region in the complex plane such that there is a nonconstant bounded holomorphic function on G, and denote the algebra of all such functions by BH{G). Let H^{G) denote the Banach algebra that arises when BH{G) is endowed with the supremum norm. In the case where G is the unit disc D, H*>(G) has been extensively studied, mostly by a real-variables analysis of the radial boundary value...
متن کاملSpectra of Weighted Algebras of Holomorphic Functions
We consider weighted algebras of holomorphic functions on a Banach space. We determine conditions on a family of weights that assure that the corresponding weighted space is an algebra or has polynomial Schauder decompositions. We study the spectra of weighted algebras and endow them with an analytic structure. We also deal with composition operators and algebra homomorphisms, in particular to ...
متن کاملCharacterization of Young Measures Generated by Functions of Bounded Deformation
This work establishes a characterization theorem for (generalized) Young measures generated by symmetric derivatives of functions of bounded deformation (BD) in the spirit of the classical Kinderlehrer–Pedregal theorem. Our result places such Young measures in duality with symmetric-quasiconvex functions with linear growth. The “local” proof strategy combines blow-up arguments with the singular...
