Axiomatisability problems for S-posets [PDF]

open access: yes, 2009
Let C be a class of algebras of a given fixed type t. Associated with the type is a first order language L_t. One can then ask the question, when is the class C axiomatisable by sentences of L_t.

On the homological classification of pomonoids: atomic posemilattices [PDF]

open access: yes, 2013
Between dierent and relatively well investigated so-called flatness properties of S-posets there is a property called property (Pw) which, so far, has not received much attention.

Induced minors and well-quasi-ordering [PDF]

open access: yes, 2018
A graph $H$ is an induced minor of a graph $G$ if it can be obtained from an induced subgraph of $G$ by contracting edges. Otherwise, $G$ is said to be $H$-induced minor-free.

NETS AND SEPARATED S-POSETS [PDF]

open access: yes, 2013
Nets, useful topological tools, used to generalize certainconcepts that may only be general enough in the context of metricspaces. In this work we introduce this concept in an $S$-poset, aposet with an action of a posemigroup $S$ on it whichis a very ...

On Morita equivalence of partially ordered semigroups with local units [PDF]

open access: yes, 2011
We show that for two partially ordered semigroups S and T with common local units, there exists a unitary Morita context with surjective maps if and only if the categories of closed right S- and T-posets are ...

Dominions, zigzags and epimorphisms for partially ordered semigroups [PDF]

open access: yes, 2014
We prove an analogue of Isbell's celebrated zigzag theorem for partially ordered semigroups. This theorem provides a useful description of dominions which we employ to describe absolute closedness of posemigroups and epimorphisms in varieties of ...

Quantaloidal Completions of Order-enriched Categories and Their Applications

open access: yes, 2022
By introducing the concept of quantaloidal completions for an order-enriched category, relationships between the category of quantaloids and the category of order-enriched categories are studied.

Uniqueness of directed complete posets based on Scott closed set lattices

open access: yes, 2018
In analogy to a result due to Drake and Thron about topological spaces, this paper studies the dcpos (directed complete posets) which are fully determined, among all dcpos, by their lattices of all Scott-closed subsets (such dcpos will be called $C_ ...

Climate Change and (Mal)Adaptation in Tourism‐Intensive Alpine Regions

open access: yesThe Political Quarterly, EarlyView.
Abstract Tourism, especially in winter, accounts for a large share of economic income in Alpine regions. At the same time, these regions are more severely affected by climate change, leading to shorter winter seasons and reduced snow cover. This presents a pressing issue for areas reliant on income from winter tourism through activities such as skiing.

Inquiry and Logical Form

open access: yesPhilosophical Perspectives, EarlyView.
ABSTRACT Joint inquiry requires agents to exchange public content about some target domain, which in turn requires them to track which content a linguistic form contributes to a conversation. But, often, the inquiry delivers a necessary truth. For example, if we are inquiring whether a particular bird, Tweety, is a woodpecker, and discover that it is ...
