Accessible Model Categories [PDF]
We prove that a weak factorization system on a locally presentable category is accessible if and only if it is small generated in the sense of R. Garner. Moreover, we discuss an analogy of Smith's theorem for accessible model categories.

The Flow Matrix Offers a Straightforward Alternative to the Problematic Markov Matrix
The Flow matrix is a novel method to describe and extrapolate transitions among categories. The Flow matrix extrapolates a constant transition size per unit of time on a time continuum with a maximum of one incident per observation during the ...

On an extension of the notion of Reedy category [PDF]
We extend the classical notion of a Reedy category so as to allow non-trivial automorphisms. Our extension includes many important examples occuring in topology such as Segal's category Gamma, or the total category of a crossed simplicial group such as ...

On the Left Properness of the Model Category of Permutative Categories
In this paper, we introduce a notion of free cofibrations of permutative categories. We show that each cofibration of permutative categories is a retract of a free cofibration.

Categories and range effects in human spatial memory
After learning a particular target stimulus, such as a location, humans’ judgements of whether a particular stimulus is the target or not is affected by the range of stimuli presented on tests.

Category of Situationality in Narrative Model of Artistic and Legal Discourse
The subject of research in this article is the specificity of the category of discursive situationality, which determined the problematics of the novel “Bleak House” by Ch. Dickens (1853).

The homotopy theory of simplicial props [PDF]
The category of (colored) props is an enhancement of the category of colored operads, and thus of the category of small categories. In this paper, the second in a series on "higher props," we show that the category of all small colored simplicial props ...

Polynomial Columns-Parameter Symmetry Model and its Decomposition for Square Contingency Tables
This study proposes a polynomial columns-parameter symmetry model for square contingency tables with the same row and column ordinal classifications. In the proposed model, the odds for all i < j that an observation will fall in row category i and column

Waldhausen K-theory of spaces via comodules [PDF]
Let $X$ be a simplicial set. We construct a novel adjunction between the categories of retractive spaces over $X$ and of $X_{+}$-comodules, then apply recent work on left-induced model category structures (arXiv:1401.3651v2 [math.AT],arXiv:1509.08154 ...

Sheafifiable homotopy model categories [PDF]
If a Quillen model category can be specified using a certain logical syntax (intuitively, ``is algebraic/combinatorial enough''), so that it can be defined in any category of sheaves, then the satisfaction of Quillen's axioms over any site is a purely formal consequence of their being satisfied over the category of sets.
