Make more knowledge even in less time every day. You may not always spend your time and money to go abroad and get the experience and knowledge by yourself. Reading is a good alternative to do in… Expand

By a finite open Riemann surface is meant a proper, open, connected subset of a compact Riemann surface W whose boundary T is also the boundary of W— X and consists of a finite number of closed… Expand

Introduction and remarks. In the theory of ?la-sets three main theorems stand out: that an na-set is universal for totally ordered sets of power not exceeding Ma, that any two n,-sets of power Ma are… Expand

Introduction. The correspondence between compact Riemann surfaces and function fields in one variable over C is well known and has been widely exploited, both in analysis and in algebraic geometry. A… Expand

0. Introduction. In this paper rings of continuous integer-valued functions are studied, with particular attention paid to their maximal residue class domains. These domains correspond bijectively to… Expand

Conway introduced the Field No of numbers, which Knuth has called the surreal numbers. No is a proper class and a real-closed field, with a very high level of density, which can be described by… Expand

Let κ:=ℵα. The following are known: two ηα-sets of power κ are isomorphic. Let α>0. Two ordered divisible Abelian groups that are ηα-sets of power κ are isomorphic, two real closed fields that are… Expand
