Some General Results and Open Questions on Palintiple Numbers

Palintiples are natural numbers which are integer multiples of their digit reversals. The most well-known base-10 example is 87912 = 4 · 21978. Using only elementary number theory we elucidate some general properties of palintiples of an arbitrary base. Palintiples naturally fall into three mutually exclusive and exhaustive classes based upon the structure of their carries. We apply our results...

The Factorization Problem: Some Known Results and Open Questions

This is a concise survey of some results and open problems concerning Wiener-Hopf factorization and almost periodic factorization of matrix functions. Several classes of discontinuous matrix functions are considered. Also sketched is the abstract framework which unifies the two types of factorization. Mathematics Subject Classification (2010). Primary 47A68; Secondary 30E25, 43A75, 45F15, 47B35 .

Some results on maximal open sets

In this paper, the notion of maximal m-open set is introduced and itsproperties are investigated. Some results about existence of maximal m-open setsare given. Moreover, the relations between maximal m-open sets in an m-spaceand maximal open sets in the corresponding generated topology are considered.Our results are supported by examples and counterexamples.

Automatic Structures — Recent Results and Open Questions

Regular languages are languages recognised by finite automata; automatic structures are a generalisation of regular languages where one also uses automatic relations (which are relations recognised by synchronous finite automata) and automatic functions (which are functions whose graph is an automatic relation). Functions and relations first-order definable from other automatic functions and re...

Some Foundational Questions concerning Differential Algebraic Groups

In this paper we solve some problems posed by Kolchin about differential algebraic groups. The main result (from which the others follow) is the embeddability of any differential algebraic group in an algebraic group. A crucial intermediate result, and one of independent interest, is a generalisation of Weil’s theorem on recovering an algebraic group from birational data, to pro-algebraic groups.
