Working in the category T of based spaces, we give the basic theory of diagram spaces and diagram spectra. These are functors D −→ T for a suitable small topological category D. When D is symmetric monoidal, there is a smash product that gives the category of D-spaces a symmetric monoidal structure. Examples include • Prespectra, as defined classically. •… (More)

With motivation from algebraic topology, algebraic geometry, and string theory, we study various topics in differential homological algebra. The work is divided into five largely independent parts: I Definitions and examples of operads and their actions II Partial algebraic structures and conversion theorems III Derived categories from a topological point… (More)

Please send any errors or comments on EKMM to mandell@math. Error: Lemma II.6.1 is false as stated and has incorrect proof. who gave the following counterexample (I have rephrased it, any errors due to me): Let S be the monad on sets that takes a set to its disjoint union with the set {1, 2}. Let T be the monad on the category of (sets under the set {1, 2})… (More)

We explain a fundamental additivity theorem for Euler characteristics and generalized trace maps in triangulated categories. The proof depends on a refined axiomatization of symmetric monoidal categories with a compatible triangulation. The refinement consists of several new axioms relating products and distinguished triangles. The axioms hold in the… (More)

We give a quick outline of a bare bones introduction to point set topology. The focus is on basic concepts and definitions rather than on the examples that give substance to the subject. 1. Topological spaces Definition 1.1. A topology on a set X is a set of subsets, called the open sets, which satisfies the following conditions. (i) The empty set ∅ and the… (More)

Let S be a symmetric monoidal category with product ⊗ and unit object κ. Definition 1. An operad C in S consists of objects C (j), j ≥ 0, a unit map η : κ → C (1), a right action by the symmetric group Σ j on C (j) for each j, and product maps γ : C (k) ⊗ C (j 1) ⊗ · · · ⊗ C (j k) → C (j) for k ≥ 1 and j s ≥ 0, where j s = j. The γ are required to be… (More)

For Saunders, with gratitude and admiration One flourishing branch of category theory, namely coherence theory, lies at the heart of algebraic K-theory. Coherence theory was initiated in MacLane's paper [13]. There is an analogous coherence theory of higher homotopies, and the classifying space construction transports categorical coherence to homotopical… (More)
