𝓜𝓝-convergence and lim-inf𝓜-convergence in partially ordered sets

Open Mathematics, 2018
In this paper, we first introduce the notion of 𝓜𝓝-convergence in posets as an unified form of O-convergence and O2-convergence. Then, by studying the fundamental properties of 𝓜𝓝-topology which is determined by 𝓜𝓝-convergence according to the standard ...

On the existence and uniqueness of a positive solution to a boundary-value problem of the Sturm-Liouville type for a nonlinear ordinary differential equation

Современная математика: Фундаментальные направления, 2023
Using the fixed point theorem in partially ordered sets, we obtain sufficient conditions for the existence of a unique positive solution to a boundary-value problem of the Sturm-Liouville type for a nonlinear ordinary differential equation, and give an ...

On a criterion of the finiteness of the representation type for families of the categories of injective representations

Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2022
The representations of posets (partially ordered sets), introduced by L. A. Nazarova and A. V. Roiter in 1972, play an important role in the modern representation theory and its applications. M. M.

Majorization on a Partially Ordered Set [PDF]

Proceedings of the American Mathematical Society, 1979
We extend the classical concept of set majorization to the case where the set is partially ordered. We give a useful property which characterizes majorization on a partially ordered set. Quite unexpectedly, the proof of this property relies on a theorem of Shapley on convex games.

Choice Overload and Height Ranking of Menus in Partially-Ordered Sets

Entropy, 2015
When agents face incomplete information and their knowledge about the objects of choice is vague and imprecise, they tend to consider fewer choices and to process a smaller portion of the available information regarding their choices.

Between quantum logic and concurrency [PDF]

Electronic Proceedings in Theoretical Computer Science, 2014
We start from two closure operators defined on the elements of a special kind of partially ordered sets, called causal nets. Causal nets are used to model histories of concurrent processes, recording occurrences of local states and of events. If every
