Left-induced model structures and diagram categories

Kathryn Hess Bellwald, Varvara Karpova, Magdalena Kedziorek

We prove existence results à la Jeff Smith for left-induced model category structures, of which the injective model structure on a diagram category is an important example. We further develop the notions of fibrant generation and Postnikov presentation fro ...

HIGHER MORSE MODULI SPACES AND n-CATEGORIES

We generalize Cohen & Jones & Segal's flow category, whose objects are the critical points of a Morse function and whose morphisms are the Morse moduli spaces between the critical points to an n-category. The n-category construction involves repeatedly doi ...

The homotopy theory of coalgebras over a comonad

Kathryn Hess Bellwald

Let K be a comonad on a model category M. We provide conditions under which the associated category of K-coalgebras admits a model category structure such that the forgetful functor to M creates both cofibrations and weak equivalences. We provide concrete ...

Hermitian Categories, Extension Of Scalars And Systems Of Sesquilinear Forms

Eva Bayer Fluckiger, Daniel Arnold Moldovan

We prove that the category of systems of sesquilinear forms over a given hermitian category is equivalent to the category of unimodular 1-hermitian forms over another hermitian category. The sesquilinear forms are not required to be unimodular or defined o ...

Creativity without critique: An inquiry into the aesthetization of the alternative culture

Luca Giovanni Pattaroni, Yves Pedrazzini, Mischa-Sébastien Piraud, Letícia Cabeçadas Do Carmo

The category of “creative city” is far from neutral. Indeed, it can be linked to very contrasted – and even opposed – practices and urban worlds. In order to grasp those differences, we need to take a closer look at what is entailed in the concepts of “cre ...

Le secteur agricole en Inde: Quelles mutations?

Le secteur agricole en Inde est à la fois en profonde mutation et sujet à de sérieuses fragilités. De fait, alors qu’il emploie aujourd’hui encore la moitié de la population active indienne, son taux de croissance est à la traîne par rapport au reste de l’ ...

Parametrized K-theory

Nicolas Mathieu Michel

In nature, one observes that a K-theory of an object is defined in two steps. First a “structured” category is associated to the object. Second, a K-theory machine is applied to the latter category that produces an infinite loop space. We develop a general ...

A Situated Approach to Systems Based Modeling of Services

Anshuman Bahadur Saxena

Situatedness refers to the imagery that conceptualization invokes. The image, as a whole, provides the context for interpreting the relevance of the categories revealed in the image. At a basic level of conceptualization, the causal relevance of an observe ...
