Corona-type theorems and division in some function algebras on planar domains

Let $A$ be an algebra of bounded smooth functions on the interior of a compact set in the plane. We study the following problem: if $f,f_1,\dots,f_n\in A$ satisfy $|f|\leq \sum_{j=1}^n |f_j|$, does there exist $g_j\in A$ and a constant $N\in\N$ such that $f^N=\sum_{j=1}^n g_j f_j$? A prominent role in our proofs is played by a new space, C_{\dbar, 1}(K), which we call the algebra of \dbar-smooth functions. In the case $n=1$, a complete solution is given for the algebras $A^m(K)$ of functions holomorphic in $K^\circ$ and whose first $m$-derivatives extend continuously to \ov{K^\circ}. This necessitates the introduction of a special class of compacta, the so-called locally L-connected sets. We also present another constructive proof of the Nullstellensatz for $A(K)$, that is only based on elementary \dbar-calculus and Wolff's method.Comment: 23 pages, 6 figure

Final Report: Talking about sex and relationships: The views of young people with learning disabilities

We ran a drama group with young people with learning disabilities. We also interviewed parents of young people with learning disabilities. We also talked to groups of teachers. There has not been much research done about this before
