Abstract

We study functions on topometric spaces which are both (metrically) Lipschitz and (topologically) continuous, using them in contexts where, in classical topology, ordinary continuous functions are used. We study the relations of such functions with topometric versions of classical separation axioms, namely, nor- mality and complete regularity, as well as with completions of topometric spaces. We also recover a compact topometric space X from the lattice of continuous 1-Lipschitz functions on X , in analogy with the recovery of a compact topological space X from the structure of (real or complex) functions on X. 2010 Mathematics Subject Classification 54D15 (primary); 54E99, 46E05 (sec- ondary)

拓扑空间上的Lipschitz函数

我们研究了拓扑空间上的(度量上的)Lipschitz函数和(拓扑上的)连续函数，并在经典拓扑中使用普通连续函数的情况下使用它们。我们研究了这类函数与经典分离公理的拓扑版本，即非不规则性和完全正则性，以及拓扑空间的完备性的关系。我们也从X上的连续1-Lipschitz函数的晶格中恢复紧致拓扑空间X，类似于从X上的(实数或复数)函数的结构中恢复紧致拓扑空间X。54E99, 46E05(二级)

期刊介绍： "Journal of Logic and Analysis" publishes papers of high quality involving interaction between ideas or techniques from mathematical logic and other areas of mathematics (especially - but not limited to - pure and applied analysis). The journal welcomes papers in nonstandard analysis and related areas of applied model theory; papers involving interplay between mathematics and logic (including foundational aspects of such interplay); mathematical papers using or developing analytical methods having connections to any area of mathematical logic. "Journal of Logic and Analysis" is intended to be a natural home for papers with an essential interaction between mathematical logic and other areas of mathematics, rather than for papers purely in logic or analysis.
