Relating Translation functor and Jacquet functor via Chan-Wong's comparison functor [PDF]

open access: yesarXiv
Kei Yuen Chan and Kayue Daniel Wong constructed a functor from the category of Harish-Chandra modules of $\GL(n, \C)$ to the category of modules over graded Hecke algebra $\H_m$ of type A. This functor has several nice properties, such as compatible with parabolic inductions, and preserving standard and irreducible objects.

Abelian categories and definable additive categories [PDF]

open access: yesarXiv, 2012
We consider three (2-)categories and their (anti-)equivalence. They are the category of small abelian categories and exact functors, the category of definable additive categories and interpretation functors, the category of locally coherent abelian categories and coherent morphisms. These categories link algebra, model theory and "geometry".

Functors on the category of quasi-fibrations

open access: yesTopology and its Applications, 2008
AbstractWe consider the following questions: when can we extend a continuous endofunctor on Top the category of topological spaces to a fibrewise continuous endofunctor on Top(2) the category of continuous maps? If this is true, does such fibrewise continuous endofunctor preserve fibrations? In this paper, we define Fib the topological category of cell-

Functors between Reedy model categories of diagrams [PDF]

open access: yesarXiv, 2015
If $D$ is a Reedy category and $M$ is a model category, the category $M^{D}$ of $D$-diagrams in $M$ is a model category under the Reedy model category structure. If $C \to D$ is a Reedy functor between Reedy categories, then there is an induced functor of diagram categories $M^{D} \to M^{C}$. Our main result is a characterization of the Reedy functors $

The definable content of homological invariants II: Čech cohomology and homotopy classification

open access: yesForum of Mathematics, Pi
