The concept of θ-closure was introduced by Velicko to study H-closed spaces and to generalize Taimanov's extension theorem [11], [12]. More recently, this notion has been used by Dickman and Porter [1] to characterize those Hausdorff spaces in which the Fomin H-closed extension operator commutes with the projective cover (absolute) operator and [2] to ...

Insertion operations: Closure properties
Bull. EATCS, 1993The paper investigates closure properties of families of languages (in Chomsky hierarchy) under various variants of insertion operations as introduced by the author [On insertion and deletion operations in formal languages, PhD Thesis, Univ. of Turku, Dept. of Math., 1991].

Conditional and Closure Properties
2001The union theorem, introduced in section 8.2.3, is the main tool for the study of asynchronous compositions of programs. The major virtue of this theorem is that it provides a simple rule for deducing the co-properties and transient predicates of a system from those of its component boxes. The major shortcoming is that it does not provide a simple rule

Closure properties of ordered languages
Bull. EATCS, 1996Summary: In this note, we solve questions regarding closure properties of ordered languages. Especially, ordered languages from a full abstract family of recursive languages which is neither intersection- nor complementation-closed.
