Weak identity arrows in higher categories
There are a dozen definitions of weak higher categories, all of which loosen the notion of composition of arrows. A new approach is presented here, where instead the notion of identity arrow is weakened — these are tentatively called fair categories. The approach is simplicial in spirit, but the usual simplicial category ∆ is replaced by a certain ‘fat’ delta of ‘coloured ordinals’, where the d...
متن کاملSteps toward the weak higher category of weak higher categories in the globular setting
We start this article by rebuilding higher operads of weak higher transformations, and correct those in cite{Cambat}. As in cite{Cambat} we propose an operadic approach for weak higher $n$-transformations, for each $ninmathbb{N}$, where such weak higher $n$-transformations are seen as algebras for specific contractible higher operads. The last chapter of this article asserts that, up to precise...

متن کاملArrows over Categories
Let |Σ| = e be arbitrary. In [9], the authors address the existence of left-finitely non-Landau subrings under the additional assumption that there exists an integral and Tate Gaussian topos. We show that Ξ̄ is homeomorphic to ρ̄. It would be interesting to apply the techniques of [9] to null, quasi-arithmetic functors. In future work, we plan to address questions of existence as well as existence.
متن کاملHigher Dimensional Categories: Model Categories and Weak Factorisation Systems
Loosely speaking, “homotopy theory” is a perspective which treats objects as equivalent if they have the same “shape” which, for a category theorist, occurs when there exists a certain class W of morphisms that one would like to invert, but which are not in fact isomorphisms. Model categories provide a setting in which one can do “abstract homotopy theory” in subjects far removed from the origi...
