Definable Tietze extension property in o-minimal expansion of ordered group

Masato Fujita

The following two assertions are equivalent for an o-minimal expansion of an ordered group . There exists a definable bijection between a bounded inter…

Quasi-quadratic modules in valuation ring and valued field

Masato Fujita, Masaru Kageyama

This is a revised version of the previous version with a new appendix consisting of characteristic two case. We define quasi-quadratic modules in a commutative ring generalizing th…

Uniformly locally o-minimal open core

Masato Fujita

This paper discusses sufficient conditions for a definably complete densely linearly ordered expansion of an abelian group having the uniformly locally o-minimal open cores of the…

Closure and Connected Component of a Planar Global Semianalytic Set Defined by Analytic Functions Definable in O-minimal Structure

Masato Fujita

We consider a global semianalytic set defined by real analytic functions definable in an o-minimal structure. When the o-minimal structure is polynomially bounded, we show that the…

Dimension inequality for a definably complete uniformly locally o-minimal structure of the second kind

Masato Fujita

Consider a definably complete uniformly locally o-minimal expansion of the second kind of a densely linearly ordered abelian group. Let be a definable map, wh…
