We consider locally o-minimal structures possessing tame topological properties shared by models of DCTC and uniformly locally o-minimal expansions of the second kind of densely …

We first show that the projection image of a discrete definable set is again discrete for an arbitrary definably complete locally o‐minimal structure. This fact together with the results in …

We define and investigate a uniformly locally o-minimal structure of the second kind in this paper. All uniformly locally o-minimal structures of the second kind have local monotonicity …

We propose new structures called almost o-minimal structures and X-structures. The former is a first-order expansion of a dense linear order without endpoints such that the intersection …

Let $\mathcal F=(F,+.\cdot,<, 0, 1,\dots) $ be a definably complete locally o-minimal expansion of an ordered field. We demonstrate the existence of definable quotients of …

This paper is devoted to o-minimalism, the study of the first-order properties of o-minimal structures. The main protagonists are the pseudo-o-minimal structures, that is to say, the …

We consider d-minimal expansions of ordered fields. We demonstrate the existence of definable quotients of definable sets by definable equivalence relations when several …
