A duality theoretic view on limits of finite structures: Extended version [PDF]
Logical Methods in Computer Science, 2022 A systematic theory of structural limits for finite models has been developed by Nesetril and Ossona de Mendez. It is based on the insight that the collection of finite structures can be embedded, via a map they call the Stone pairing, in a space of ...

Advanced techniques for pancreaticobiliary stone extraction
VideoGIE, 2020 Background and Aims: Pancreaticobiliary stone extraction during endoscopic retrograde cholangiopancreatography can be challenging when working space is limited or the duct is irregular and strictured.

Codensity and stone spaces [PDF]
Mathematica Slovaca, 2018 AbstractWe present a detailed computation of two codensity monads associated to two canonical functors – the inclusion functor ofFinSetintoTopand the inclusion functor of the category of the powers of the Sierpiński space intoTop. We show that the categories of algebras of the two monads are the categories of Stone spaces and of sober spaces ...

Land, 2021 Desertification is a serious threat to human survival and to ecosystems, especially to inland desert oases. An assessment of desertification severity is essential to ensure national sustainable development for agricultural and land expansion processes in

Stone Enclosures —Linking Time and Guiding Space
Current Swedish Archaeology, 1996 From the late Roman Iron Age, stone enclosures and houses with a stone foundation have been built on Gotland. Stone enclosures have generally been interpreted as fences between the infields and the outlying land.

Disconnection in the Alexandroff duplicate
Applied General Topology, 2021 It was demonstrated in [2] that the Alexandroff duplicate of the Čech-Stone compactification of the naturals is not extremally disconnected. The question was raised as to whether the Alexandroff duplicate of a non-discrete extremally disconnected space ...

Вестник Научно-исследовательского института железнодорожного транспорта, 2019 Strength properties of mineral materials used in the track operation, which are crushed stone and sand, do not depend on the ambient temperature (up to 500 °C) and humidity, but gradually degrade when its pore space becomes clogged with fines, oil ...

A Stone-Cech Compactification for Limit Spaces [PDF]
Proceedings of the American Mathematical Society, 1970 Wyler (Notices Amer. Math. Soc. 15 (1968), 169. Abstract #653-306.) has given a Stone-tech compactification for limit spaces. However, his is not necessarily an embedding. Here, it is shown that any Hausdorff limit space (X, r) can be embedded as a dense subspace of a compact, Hausdorff, limit space (X1, ri) with the following property: any continuous ...

Proceedings of International Mathematical Sciences, 2023 The goal of this paper is to characterize each of compact, totally disconnected, Stone relation spaces, and Stone reflexive spaces as well as examine the relationships between them. Finally, we investigate some properties of them and compare our results.
