A Characterization of One-component Inner Functions

Artur Nicolau, Atte Reijonen

We present a characterization of one-component inner functions in terms of the location of their zeros and their associated singular measure. As consequence we answer several quest…

Besov spaces induced by doubling weights

Atte Reijonen

Let $1 \leq p < \infty$ , $0 < q < \infty$ and $ν$ be a two-sided doubling weight satisfying $0 \leq r < 1 sup \frac{( 1 - r ) ^{q}}{\int _{r}^{1} ν ( t ) d t} \int_{0}^{r} \frac{ν ( s )}{( 1 - s ) ^{q}} d s < \infty.$ The…

Remarks on one-component inner functions

Atte Reijonen

A one-component inner function $Θ$ is an inner function whose level set $Ω_{Θ} (ε) = {z \in D : ∣Θ (z) ∣ < ε}$ is connected for some $ε \in (0, 1)$ . We…
