Heavily separable functors [PDF]
Journal of Algebra, 2020 Prompted by an example related to the tensor algebra, we introduce and investigate a stronger version of the notion of separable functor that we call heavily separable. We test this notion on several functors traditionally connected to the study of separability.

On the Casselman-Jacquet functor [PDF]
, 2019 We study the Casselman-Jacquet functor $J$, viewed as a functor from the (derived) category of $(\mathfrak{g},K)$-modules to the (derived) category of $(\mathfrak{g},N^-)$-modules, $N^-$ is the negative maximal unipotent.

Proceedings of the American Mathematical Society, 1972 We show that natural transformations play the role of homotopy for (covariant) functors. Homotopic functors are shown to induce identical maps between the homology groups of categories. For a space X, there is an associated category AS(X). We show that the classifying space of AS(X) has the same homotopy type as X if X is a CW complex.

由度量空间诱导的*-拓扑和s-拓扑(* -Topology and s-topology induced by metric space)
Zhejiang Daxue xuebao. Lixue ban, 2018 This paper studies * -topology and s-topology in polysaturated nonstandard model,which are induced by metric space on two nonstandard sets. In order to construct * -topology , the set of finite points is introduced.

Generalized Burnside-Grothendieck ring functor and aperiodic ring functor associated with profinite groups [PDF]
, 2004 For every profinite group $G$, we construct two covariant functors $\Delta_G$ and ${\bf {\mathcal {AP}}}_G$ from the category of commutative rings with identity to itself, and show that indeed they are equivalent to the functor $W_G$ introduced in [A ...

The family Floer functor is faithful [PDF]
, 2014 Family Floer theory yields a functor from the Fukaya category of a symplectic manifold admitting a Lagrangian torus fibration to a (twisted) category of perfect complexes on the mirror rigid analytic space.

Some topological properties of the spaces expX, λX and NX [PDF]
Mathematica Moravica, 2017 In this paper we prove that the exponential functor exp and the functor of superextension λ preserve some topological properties with respect to the topology of any T1 -space, and the functor of complete linked systems N preserves some topological ...

Hopf and Lie algebras in semi-additive Varieties [PDF]
Logical Methods in Computer Science, 2017 We study Hopf monoids in entropic semi-additive varieties with an emphasis on adjunctions related to the enveloping monoid functor and the primitive element functor.

On $\ast$-measure monads on the category of ultrametric spaces
Karpatsʹkì Matematičnì Publìkacìï, 2022 The functor of $\ast$-measures of compact support on the category of ultrametric spaces and non-expanding maps is introduced in the previous publication of the authors.

Interpolation in Term Functor Logic
Crítica, 2023 Given some links between Lyndon’s Interpolation Theorem, term distribution, and Sommers and Englebretsen’s logic, in this contribution we attempt to capture a sense of interpolation for Sommers and Englebretsen’s Term Functor Logic.
