Towards free localic algebras [PDF]

Categories and General Algebraic Structures with Applications
The purpose of this paper is to establish that the underlying objectfunctor from the models of a Lawvere theory to the base category creates limitsand coequalisers of all parallel pairs of homomorphisms whose underlying pairadmit a split coequaliser.

The categorical contours of the Chomsky-Sch\"utzenberger representation theorem [PDF]

Logical Methods in Computer Science
We develop fibrational perspectives on context-free grammars and on nondeterministic finite-state automata over categories and operads. A generalized CFG is a functor from a free colored operad (aka multicategory) generated by a pointed finite species ...

Erratum to "Homotopy in Functor Categories" [PDF]

Transactions of the American Mathematical Society, 1983
J*LanjJ*X J*LanJA = C o (JOP X J) cA ?J*X kJ*9 J*X J*X is a 2-cofibration. Since J* is a left adjoint, the lower square is a pushout. Since (J*eX)71J*X = 1, the conclusion follows in routine fashion. The additional hypothesis asks to be characterized as the assertion that C' C C is a cofibered subcategory. There have been other uses of the adjective in

Lattice of compactifications of a topological group [PDF]

Categories and General Algebraic Structures with Applications, 2019
We show that the lattice of compactifications of a topological group $G$ is a complete lattice which is isomorphic to the lattice of all closed normal subgroups of the Bohr compactification $bG$ of $G$.

The Nachbin compactification via convergence ordered spaces

International Journal of Mathematics and Mathematical Sciences, 1993
We construct the Nachbin compactification for a T3.5-ordered topological ordered space by tailing a quotient of an ordered convergence space compactification.

On exact category of $(m, n)$-ary hypermodules [PDF]

Categories and General Algebraic Structures with Applications, 2020
We introduce and study category of $(m, n)$-ary hypermodules as a generalization of the category of $(m, n)$-modules as well as the category of classical modules. Also, we study various kinds of morphisms.

Fuzzy TL-uniform spaces

International Journal of Mathematics and Mathematical Sciences, 2006
The main purpose of this paper is to introduce a new structure that is a fuzzy TL-uniform space. We show that our structure generates a fuzzy topological space, precisely, a fuzzy T-locality space.
