A Complexity Theory for Feasible Closure Properties
The study of the complexity of sets encompasses two complementary aims: (1) establishing-usually via explicit construction of algorithms-that sets are feasible, and (2) studying the relative complexity of sets that plausibly might be feasible but are not

Closure Properties of Synchronized Relations. [PDF]
A standard approach to define k-ary word relations over a finite alphabet A is through k-tape finite state automata that recognize regular languages L over {1, ..., k} x A, where (i,a) is interpreted as reading letter a from tape i. Accordingly, a word w in L denotes the tuple (u_1, ..., u_k) in (A^*)^k in which u_i is the projection of w onto i ...

Nest sets and relativized closure properties
AbstractA nest set is the language generated by a context-free grammar whose rules are A → aBāC or A → ϵ (where a, ā are paired terminal symbols, and A, B, C are nonterminal symbols). They can be seen as the one-dimensional expressions of the recognizable sets of binary trees. We study their closure properties under relativized operations with respect

Closure properties of Watson-Crick grammars [PDF]
In this paper, we define Watson-Crick context-free grammars, as an extension of Watson-Crick regular grammars and Watson-Crick linear grammars with context-free grammar rules.

Modularity and Combination of Associative Commutative Congruence Closure Algorithms enriched with Semantic Properties [PDF]
Algorithms for computing congruence closure of ground equations over uninterpreted symbols and interpreted symbols satisfying associativity and commutativity (AC) properties are proposed. The algorithms are based on a framework for computing a congruence

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

δω-Continuity and some Results on δω-Closure Operator
Al-Jarrah et al. defined a new topological operator, namely, δω-closure operator, and proved that it lies between the δ-closure operator and the usual closure operator. Al-Ghour et al. defined θω-closure operator and discussed its properties.

Properties of Discrete Reversed Aging Intensity Function [PDF]
In this paper, we discuss the properties of reversed aging intensity (RAI) function for discrete random variable and study its nature for some distributions. Further, using this function we characterize some discrete related distributions.

Closure Properties of Coalgebra Automata [PDF]
We generalize some of the central results in automata theory to the abstraction level of coalgebras. In particular, we show that for any standard, weak pullback preserving functor F, the class of recognizable languages of F -coalgebras is closed under taking unions, intersections and projections.
