Commutative Unary Algebras with Join-Semidistributive Topology Lattices

Lobachevskii Journal of Mathematics, 2020
A unary algebra \(\mathcal A=(A,\Omega)\) is called commutative if any two basic operations commute. For an algebra \(\mathcal A\), let \(\mathcal T(\mathcal A))\) be the set of all topologies on \(\mathcal A\). It is known that \(\mathcal T(\mathcal A))\) forms a complete lattice under inclusion. The main result of the paper is Theorem~1.

Generalized Topological Representation for Complete Join-Semilattices

Acta Mathematica Hungarica, 2014
The well-known adjunction between topological spaces and frames is extended to that between generalized topological spaces and complete join-semilattices. Here, generalized topological spaces are taken in the sense of Császár, i.e., given by a set of subsets closed under unions.

Active and Concurrent Topology Maintenance [PDF]

International Symposium on Distributed Computing, 2004
A central problem for structured peer-to-peer networks is topology maintenance, that is, how to properly update neighbor variables when nodes join and leave the network, possibly concurrently.

Orchestrating Transactions in Join Calculus

International Conference on Concurrency Theory, 2002
We discuss the principles of distributed transactions, then we define an operational model which meets the basic requirements and we give a prototyping implementation for it in join-calculus.

Topological, simplicial and categorical joins

Archiv der Mathematik, 2004
This paper gives a tour of join constructions for topological spaces, simplicial sets and small categories, with evident comparisons. The unifying theme is that the join of two objects \(X\) and \(Y\) is the homotopy colimit of the diagram of projections \(X \leftarrow X \times Y \to Y\).

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.

Interpolatory Subdivision on Open Quadrilateral Nets with Arbitrary Topology

Computer graphics forum (Print), 1996
A simple interpolatory subdivision scheme for quadrilateral nets with arbitrary topology is presented which generates C 1 surfaces in the limit. The scheme satis es important requirements for practical applications in computer graphics and engineering ...

Parallel in-memory trajectory-based spatiotemporal topological join

2015 IEEE International Conference on Big Data (Big Data), 2015
The rapid growth of spatiotemporal Big Data is fueling the emergence and growth of many applications. Many of these applications are characterized by complex spatiotemporal queries. An important category of such queries is the trajectory-based spatiotemporal topological join queries, which combine a trajectory dataset and a spatial objects dataset ...
