Entropy of Closure Operators and Network Coding Solvability
Entropy, 2014 The entropy of a closure operator has been recently proposed for the study of network coding and secret sharing. In this paper, we study closure operators in relation to their entropy. We first introduce four different kinds of rank functions for a given

Topology and its Applications, 1987 Closure operators form a familiar tool in topology. The authors introduce an abstract notion of closure operator in the realm of arbitrary categories. It turns out that there is a close connection between closure operators and factorization structures (for sinks).

Transcatheter closure of PDA: how the pathway changed from classical fluoroscopy approach [PDF]
Frontiers in Cardiovascular MedicinePatent ductus arteriosus (PDA) is a common congenital cardiac defect traditionally managed by surgical and transcatheter closure under fluoroscopic guidance. Over recent years, significant advances in imaging modalities, device technology, and procedural

CLOSURE OPERATORS ON BL-ALGEBRAS [PDF]
Communications of the Korean Mathematical Society, 2004 Summary: We study relationships between closure operators and BL-algebras. We investigate the properties of closure operators and BL-homomorphisms on BL-algebras. We show that the image of a closure operator on a BL-algebra is isomorphic to a quotient BL-algebra.

Lattices of closure operators [PDF]
Discrete Mathematics, 1998 The system of all closure operators on a set \(V\) forms in a natural way a lattice which is isomorphic to the lattice of all Moore families \((\text{MF}(V),\subseteq)\) of subsets of \(V\). The author shows the existence of a spanning tree for the lattice of Moore families.

Pseudocomplements of closure operators on posets
Discrete Mathematics, 2002 The author gives some new results of pseudocomplementation in the more general setting of closure operators on mere posets. He proves that if \(P\) is a meet-continuous meet-semilattice, then \(\text{uco}(P)\) is a pseudocoplemented complete lattice.

Sobre o operador de fecho, um conceito que permeia muitos e distintos tópicos matemáticos
Intermaths, 2022 We present the closure operators and detach several distinct topics of mathematics in which we can observe the action of these closure operators. So, we can see these operators as a trans-topic concept. Considering that these mathematics theories can be

Internal Neighbourhood Structures II: Closure and closed morphisms [PDF]
Categories and General Algebraic Structures with Applications, 2023 Internal preneighbourhood spaces inside any finitely complete category with finite coproducts and proper factorisation structure were first introduced in \cite{2020}.

Applications of operations on generalized topological spaces [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 In this paper γµ -open sets and γµ -closed sets in a GTS (X, µ) have been studied, where γµ is an operation from µ to P(X). In general, collection of γµ -open sets is smaller than the collection of µ-open sets. The condition under which both are
