Simultaneous uniformization

Simultaneous Uniformization by Lipman Bers

We shall show that any two Riemann surfaces satisfying a certain condition, for instance, any two closed surfaces of the same genus g > l , can be uniformized by one group of fractional linear transformations (Theorem 1). This leads, in conjunction with previous results [2; 3] , to the simultaneous uniformization of all algebraic curves of a given genus (Theorems 2-4). Theorem 5 contains an app...

Uniformization and Anti-uniformization Properties of Ladder Systems

Let S denote a stationary subset of limit ordinals of ω1. A ladder system on S is a sequence {Lα : α ∈ S} such that each Lα is an unbounded subset of α of order type ω. A ladder system is uniformizable if for each sequence 〈fα : α ∈ S〉 of functions fα : Lα → ω there is an F : ω1 → ω such that F Lα =∗ fα for each α ∈ S. I.e., for each α ∈ S, {β ∈ Lα : F (β) 6= fα(β)} is finite. We now formulate ...

Adaptive Uniformization: Technical Details

This paper discusses technical aspects related to adaptive uniformization [1]. We give the derivation of the schemes that we have used to compute the jump probabilities. We also give some more detailed results about the complexity of adaptive uniformization. This paper is not self contained, but is a supplement to [1]. A. P. A. van Moorsel has been supported by the Netherlands Organization for ...

Inseparable Local Uniformization

The aim of this paper is to prove that an algebraic variety over a field can be desingularized locally along a valuation after a purely inseparable alteration. Zariski was first to study the problem of desingularizing algebraic varieties along valuations. He called this problem local uniformization of valuations and observed that it should be considered as the local part of the desingularizatio...
