Some Questions

These are some questions I am every interested in. Your solution to any question in this draft would be welcome. I keep updating this draft. 1. Classical recursion theory We use R to denote the partial ordering of r.e. degrees and Dn to denote the partial ordering of n-r.e. degrees. Yang and I proved thatR is not a Σ1-substructure of Dn. Question 1.1 (Khoussainov). For n > 1, is there a functio...

Clustering Word Pairs to Answer Analogy Questions

We focus on answering word analogy questions by using clustering techniques. The increased performance in answering word similarity questions can have many possible applications, including question answering and information retrieval. We present an analysis of clustering algorithms’ performance on answering word similarity questions. This paper’s contributions can be summarized as: (i) casting ...

Some Questions in Algebraic Geometry

Frans Oort \Een zot kan meer vragen \One fool can ask more questions dan tien wijzen kunnen beantwoorden." than ten wise men can answer." Een oud Nederlands spreekwoord. An old Dutch saying. Introduction In June 1995 several mathematicians will gather in Utrecht for a conference on \Arithmetic and geometry of abelian varieties," and this seems a good occasion to share with them some of the ques...

Some Questions on Unique

The simplest type of integral extension of a unique factorization domain B is obtained by adjoining to B an n-th root of one of its elements; that is, by forming the ring Bn = B[z]=(z n g), where n 2 Z and g 2 B. When n = 1, Bn = B. When n 2 it is natural to ask for what g 2 B will unique factorization be preserved? The case where B is a polynomial ring over an algebraically closed eld k immedi...
