On the topology of the joined point-pairs of an algebraic variety [PDF]

Annali di Matematica Pura ed Applicata, 1955
Data una varieta complessa non singolare V, si puo definire unacoppia congiunta di punti di V. Nel caso ove V e una varieta razionale, di un tipo molto ristretto (§ 2), si considerano le proprieta topologiche dell'insieme di coppie congiunte. Questo e uno spazio fibrato, il che rende possibile la determinazione dei suoi gruppi di omologia.

Commutative Unary Algebras with Join-Semidistributive Topology Lattices

Lobachevskii Journal of Mathematics, 2020
In this paper, it is proved that a commutative unary algebra with join-semidistributive topology lattice either is two-element or any two monogenic subalgebras of this algebra are comparable under inclusion. We also describe the class of all algebras with one unary operations whose topology lattices are join-semidistributive.

Join-meet preserving maps and Alexandrov fuzzy topologies

Journal of Intelligent & Fuzzy Systems, 2015
In this paper, we investigate the properties of join-meet preserving maps in complete residuated lattices. We define join-meet approximation operators as a generalization of fuzzy rough sets in complete residuated lattices. Moreover, we investigate the relations between join-meet preserving maps and Alexandrov fuzzy topologies. We give their examples.

Efficient Active SLAM Based on Submap Joining, Graph Topology and Convex Optimization

2018 IEEE International Conference on Robotics and Automation (ICRA), 2018
The active SLAM problem considered in this paper aims to plan a robot trajectory for simultaneous localization and mapping (SLAM) as well as for an area coverage task with robot pose uncertainty. Based on a model predictive control (MPC) framework, these two problems are solved respectively by different methods.

Topology-aware Parallel Joins

Proceedings of the ACM on Management of Data
We study the design and analysis of parallel join algorithms in a topology-aware computational model. In this model, the network is modeled as a directed graph, where each edge is associated with a cost function that depends on the data transferred between the two endpoints and the link bandwidth.

Generalized Topological Representation for Complete Join-Semilattices [PDF]

Acta Mathematica Hungarica, 2014
This paper describes a generalization of the Papert–Papert–Isbell adjunction between topological spaces and frames to a generalized one between the category of generalized topological spaces and the category of complete join-semilattices. Within these categories we aim to study certain separation axioms in a categorical point of view.

Topological, simplicial and categorical joins

Archiv der Mathematik, 2004
We examine different constructions for the join of two topological spaces, simplicial sets and small categories. We give a systematic account of this and try to clarify the interrelations between the various constructions as much as possible. In particular, we compare two standard versions of the join of simplicial sets proving results which apparently

You Shall Not Join: A Measurement Study of Cryptocurrency Peer-to-Peer Bootstrapping Techniques

Conference on Computer and Communications Security, 2019
Cryptocurrencies are digital assets which depend upon the use of distributed peer-to-peer networks. The method a new peer uses to initially join a peer-to-peer network is known as bootstrapping.
