Let ($X, L$) be a polarized 3-fold over the complex number field. In [Fk3], we proved that$g(L)≥q(X)$if$h$^{0}($L$)≥2 and moreover we classified ($X, L$) with$h$^{0}($L$)≥3 and$g(L)$=$q(X)$, where$g(L)$is the sectional genus of ($X, L$) and$q$($X$)=dim$H$^{1}($O$_{$X$}) the irregularity of$X$. In this paper we will classify polarized 3-folds ($X, L$) with$h$^{0}($L$)≥4 and$g(L)$=$q(X)$+1 by the method of [Fk3].

The$H$^{$p$}corona problem is the following: Let$g$_{1}, ...,$g$_{$m$}be bounded holomorphic functions with 0<δ≤Σ‖$g$_{$i$}‖. Can we, for any$H$^{$p$}function ϕ, find$H$^{$p$}functions$u$_{1}, ...,$u$_{$m$}such that Σ$g$_{$i$}$u$_{$i$}=ϕ? It is known that the answer is affirmative in the polydisc, and the aim of this paper is to prove that it is in non-degenerate analytic polyhedra. To prove this, we construct a solution using a certain integral representation formula. The$H$^{$p$}estimate for the solution is then obtained by localization and some harmonic analysis results in the polydisc.

We show that a compact, connected set which has uniform oscillations at all points and at all scales has dimension strictly larger than 1. We also show that limit sets of certain Kleinian groups have this property. More generally, we show that if$G$is a non-elementary, analytically finite Kleinian group, and its limit set Λ($G$) is connected, then Λ($G$) is either a circle or has dimension strictly bigger than 1.
