1876. Masato Fujita Definable Tietze extension property in o-minimal expansion of ordered group E-mail: Submission date: 3 November 2020 Abstract: The following two assertions are equivalent for an o-minimal expansion of an ordered group M=(M,<,+,0,...). There exists a definable bijection between a bounded interval and an unbounded interval. Any definable continuous function f:A → M defined on a definable closed subset of M^n has a definable continuous extension F:M^n → M. Mathematics Subject Classification: 03C64 Keywords and phrases: |
