Good Functors... are Those Preserving Philosophy

چکیده
The aim of this paper is to prevent the abstract data type researcher from an improper, naive use of category theory. We mainly emphasize some unpleasant properties of the synthesis functor when dealing with so-called loose semantics in a hierarchical approach. All our results and counter-examples are very simple, nevertheless they shed light on many common errors in the abstract specification field. We also summarize some properties of the category of models “protecting predefined sorts.”

Abstract Initiality
initiality Lutz Schröder, Horst Herrlich Abstract. We study morphisms that are initial w.r.t. all functors in a given conglomerate. Several results and counterexamples are obtained concerning the relation of such properties to different notions of subobject. E.g., strong monomorphisms are initial w.r.t. all faithful adjoint functors, but not necessarily w.r.t. all faithful monomorphism-preservi...
متن کاملProduct Preserving Functors of Infinite Dimensional Manifolds
The theory of product preserving functors and Weil functors is partly extended to infinite dimensional manifolds, using the theory of C∞-algebras.

In this paper we classify endofunctors on the simplex category, and we identify those that induce weak equivalence preserving functors on the category of simplicial sets.
متن کاملCubical Sets and Trace Monoid Actions
This paper is devoted to connections between trace monoids and cubical sets. We prove that the category of trace monoids is isomorphic to the category of generalized tori and it is a reflective subcategory of the category of cubical sets. Adjoint functors between the categories of cubical sets and trace monoid actions are constructed. These functors carry independence preserving morphisms in th...
متن کاملOn Corecursive Algebras for Functors Preserving Coproducts
For an endofunctor H on a hyper-extensive category preserving countable coproducts we describe the free corecursive algebra on Y as the coproduct of the final coalgebra for H and the free Halgebra on Y . As a consequence, we derive that H is a cia functor, i.e., its corecursive algebras are precisely the cias (completely iterative algebras). Also all functors H(−) + Y are then cia functors. For...
