Holomorphic functions with large cluster sets

نویسندگان

چکیده

We study linear and algebraic structures in sets of bounded holomorphic functions on the ball which have large cluster at every possible point (i.e., sphere several complex variables closed unit bidual infinite dimensional case). show that this set is strongly c-algebrable for all separable Banach spaces. For specific spaces including ℓ p or duals Lorentz sequence spaces, we c-algebrability spaceability even subalgebra uniformly continous ball.

Maximal cluster sets on spaces of holomorphic functions

In this paper, which has an expository nature, we consider the so called cluster sets, that is the set of accumulation points of the set of values taken by a (usually, holomorphic) function on prescribed subsets. We are specially interested in the action of holomorphic operators in order to obtain maximal cluster sets, see below for details. Extensions of classical cluster sets, where they are ...

Large subspaces of compositionally universal functions with maximal cluster sets

Let (φn) be a sequence of holomorphic self-maps of a Jordan domain G in the complex plane. Under appropriate conditions on (φn), we construct an H(G)-dense linear manifold –as well as a closed infinite-dimensional linear manifold– all of whose non-zero functions have H(G)-dense orbits under the action of the sequence of composition operators associated to (φn). Simultaneously, these functions a...

On Large Values of L Holomorphic Functions

The solution to (1.1) gives the value of the Bergman kernel function associated to Ω (the kernel of the operator projecting L(Ω) orthogonally onto O(Ω)) at (p, p). If n = 1, it is a classical fact that MΩ(p) is bounded, from above and below, by a constant factor times dist(p, bΩ)−2. In higher dimensions, the geometry of bΩ influences the size of MΩ(p) in non-trivial ways. A general lower bound ...

Primitive Sets with Large Counting Functions

A set of positive integers is said to be primitive if no element of the set is a multiple of another. If S is a primitive set and S(x) is the number of elements of S not exceeding x, then a result of Erdős implies that ∫∞ 2 (S(t)/t log t) dt converges. We establish an approximate converse to this theorem, showing that if F satisfies some mild conditions and ∫∞ 2 (F (t)/t log t) dt converges, th...
