Grothendieck rings for Lie superalgebras and the Duflo–Serganova functor [PDF]
Algebra & Number Theory, 2016 We show that the Duflo-Serganova functor on the category of finite-dimensional modules over a finite-dimensional contragredient Lie superalgebra induces a ring homomorphism on a natural quotient of the Grothendieck ring, which is isomorphic to the ring ...

Agreement, disagreement and the NP vs. DP debate
Glossa, 2020 Of special relevance for the NP vs. DP debate are nominals in which the determiner has other values for number, gender, case and/or person than the noun, for depending on whether such nominals share these values with the noun or with the determiner they ...

Functors Induced by Cauchy Extension of C$^ast$-algebras [PDF]
Sahand Communications in Mathematical Analysis, 2019 In this paper, we give three functors $mathfrak{P}$, $[cdot]_K$ and $mathfrak{F}$ on the category of C$^ast$-algebras. The functor $mathfrak{P}$ assigns to each C$^ast$-algebra $mathcal{A}$ a pre-C$^ast$-algebra $mathfrak{P}(mathcal{A})$ with completion $

t-structures for relative D-modules and t-exactness of the de Rham functor [PDF]
, 2018 This paper is a contribution to the study of relative holonomic D-modules. Contrary to the absolute case, the standard t-structure on holonomic D-modules is not preserved by duality and hence the solution functor is no longer t-exact with respect to the

On an adjoint functor to the Thom functor [PDF]
Proceedings of the American Mathematical Society, 2001 We construct a right adjoint functor to the Thom functor, i.e., to the functor which assigns the Thom space T ξ T\xi to a vector bundle ξ \xi .

N-complexes as functors, amplitude cohomology and fusion rules [PDF]
, 2006 We consider N-complexes as functors over an appropriate linear category in order to show first that the Krull-Schmidt Theorem holds, then to prove that amplitude cohomology only vanishes on injective functors providing a well defined functor on the ...

On the surjectivity of the map of spectra associated to a tensor‐triangulated functor [PDF]
, 2017 We prove a few results about the map Spc(F) induced on tensor‐triangular spectra by a tensor‐triangulated functor F . First, F is conservative if and only if Spc(F) is surjective on closed points. Second, if F detects tensor‐nilpotence of morphisms, then

A COMPUTABLE FUNCTOR FROM GRAPHS TO FIELDS [PDF]
Journal of Symbolic Logic (JSL), 2015 Fried and Kollár constructed a fully faithful functor from the category of graphs to the category of fields. We give a new construction of such a functor and use it to resolve a longstanding open problem in computable model theory, by showing that for ...

Theory and Applications of Categories, 2019 A simple criterion for a functor to be finitary is presented: we call $F$ finitely bounded if for all objects $X$ every finitely generated subobject of $FX$ factorizes through the $F$-image of a finitely generated subobject of $X$. This is equivalent to $F$ being finitary for all functors between `reasonable' locally finitely presentable categories ...

Classifying affine line bundles on a compact complex space
Complex Manifolds, 2019 The classification of affine line bundles on a compact complex space is a difficult problem. We study the affine analogue of the Picard functor and the representability problem for this functor. Let be a compact complex space with .
