Sliding Functor and Polarization Functor for Multigraded Modules [PDF]
Communications in Algebra, 2012 We define "sliding functors", which are exact endofunctors of the category of multi-graded modules over a polynomial ring. They preserve several invariants of modules, especially the (usual) depth and Stanley depth. In a similar way, we can also define the "polarization functor".

A simplification functor for coalgebras
International Journal of Mathematics and Mathematical Sciences, 2006 For an arbitrary-type functor F, the notion of split coalgebras, that is, coalgebras for which the canonical projections onto the simple factor split, generalizes the well-known notion of simple coalgebras. In case F weakly preserves kernels, the passage

Renormalization as a functor on bialgebras
Journal of Pure and Applied Algebra, 2007 The Hopf algebra of renormalization in quantum field theory is described at a general level. The products of fields at a point are assumed to form a bialgebra B and renormalization endows T(T(B)^+), the double tensor algebra of B, with the structure of a noncommutative bialgebra. When the bialgebra B is commutative, renormalization turns S(S(B)^+), the

On monomorphic topological functors with finite supports
Karpatsʹkì Matematičnì Publìkacìï, 2013 We prove that a monomorphic functor $F:\mathbf{Comp}\to\mathbf{Comp}$ with finite supports isepimorphic, continuous, and its maximal $\emptyset$-modification $F^\circ$ preserves intersections.

General Topology and its Applications, 1975 AbstractThe concepts of continuity and Čech continuity for functors on the homotopy category of topological spaces are so defined as to be equivalent, thereby extending a theorem already known for the homotopy category of compact Hausdorff spaces.

On the Derived Functors of Destabilization and of Iterated Loop Functors [PDF]
, 2017 These notes explain how to construct small functorial chain complexes which calculate the derived functors of destabilization (respectively iterated loop functors) in the theory of modules over the mod 2 Steenrod algebra; this shows how to unify results of Singer and of Lannes and Zarati.

Distribution Tableaux, Distribution Models
Axioms, 2020 The concept of distribution is a concept within traditional logic that has been fundamental for the syntactic development of Sommers and Englebretsen’s term functor logic, a logic that recovers the term syntax of traditional logic.

Equivariant extensions of *-algebras
, 2010 A bivariant functor is defined on a category of *-algebras and a category of operator ideals, both with actions of a second countable group $G$, into the category of abelian monoids. The element of the bivariant functor will be $G$-equivariant extensions
