GLOBAL CLOSURE OPERATORS VS. SUBCATEGORIES
Autor: G. E. Strecker, G. Castellini
Publikováno v: Quaestiones Mathematicae. 13:417-424
Given a concrete category (A,U) over a category X, we establish a Galois correspondence between subcategories of A and global closure operators over A.

FAITHFULNESS VS. TOPOLOGICITY
Autor: T. Titcomb, G. E. Strecker
Publikováno v: Quaestiones Mathematicae. 6:255-264
The fact that faithful functors are intimately connected with functors of topological type has been known for scene time. Here, we make the connection precise by introducing the notion of relatively topological functors, and characterize faithful fun

GRAPHIC EXTENSIONS OF MAPPINGS
Autor: F. A. Delahan, G. E. Strecker
Publikováno v: Quaestiones Mathematicae. 2:401-417
Given a mapping f: X → Y and an extension e: X → [Xtilde] of X, the restriction of the projection Π: [Xtilde] X Y → Y to the closure of the graph of f in [Xtilde] X Y is called the graphic extension of f with respect to e. It is shown that thi

Equivalence of Topologically-Algebraic and Semi-Topological Functors
Autor: T. Titcomb, R. Nakagawa, H. Herrlich, G. E. Strecker
Publikováno v: Canadian Journal of Mathematics. 32:34-39
Throughout let be faithful.1.1. A U-morphism with domain X is a pair (e, A), where e ∈ Hom (X, UA). A [U-morphism (e, A) is called U-epi ( = generating) provided that r, s ∈ Hom (A, A’) and (Ur)e = (Us)e imply that r = s.1.2. A U-source is a pa

Realization of cartesian closed topological hulls
Autor: Jiří Adámek, G. E. Strecker, J. Reiterman
Publikováno v: Manuscripta Mathematica. 53:1-33
The cartesian closed topological (CCT) hull of a concrete categoryK is the smallest full CCT extension ofK. A general method for describing the CCT hulls is presented and applied to render unified proofs for the basic examples ofK: topological spaces

On the structure of factorization structures
Autor: G. E. Strecker, A. Melton
Publikováno v: Lecture Notes in Mathematics ISBN: 9783540119616
For any category K we investigate the family of all factorization structures on K. In particular, for each such structure, (E,M), we investigate the complete lattice of all factorization structures on K with left factor a subclass of E; this investig
