Categorical Algebra
1. Introduction. Category, functor, and natural transformation of functors are notions of great generality—and consequent simplicity. They apply to many different parts of mathematics. Now 22 years old, they have recently attracted especially active interest in many quarters. This interest is probably a reflection of the very rapid current proliferation of mathematical ideas—a situation favorin...
متن کاملInteracting Quantum Observables: Categorical Algebra and Diagrammatics
Within an intuitive diagrammatic calculus and corresponding highlevel category-theoretic algebraic description we axiomatise complementary observables for quantum systems described in finite dimensional Hilbert spaces, and study their interaction. We also axiomatise the phase shifts relative to an observable. The resulting graphical language is expressive enough to denote any quantum physical s...
متن کاملInternal Categorical Structures in Homotopical Algebra
This is a survey on the use of some internal higher categorical structures in algebraic topology and homotopy theory. After providing a general view of the area and its applications, we concentrate on the algebraic modelling of connected (n + 1)-types through cat-groups.
متن کاملOperads from the viewpoint of categorical algebra
We exhibit a parallel between Lawvere’s algebraic theories and operads; there is a common ancestor of both notions whose syntax is described by labeled trees, dummy variables corresponding to special labels. Operads, cyclic and braided operads alike arise as group objects in the category of compositional structures. Laplaza’s coherence theorem for “associativity not an isomorphism” is seen to c...
متن کاملGeneralized Morita Theories The power of categorical algebra
A solution to the problem posed by Isbell in the early 1970s of how to determine all varieties (in the sense of universal algebra) equivalent to a given variety is presented. The method is based on the use of Lawvere theories. It is shown how the known characterizations of rings, Morita equivalent to a given one, and of monoids, Morita equivalent to a given one, and also how (even an extension ...
