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 ...

On Extension Of Functors [PDF]
, 2011 A.Chigogidze defined for each normal functor on the category Comp an extension which is a normal functor on the category Tych. We consider this extension for any functor on the category Comp and investigate which properties it preserves from the ...

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 ...

On paracompact spaces and projectively inductively closed functors
Applied General Topology, 2002 In this paper we introduce a notion of projectively inductively closed functor (p.i.c.-functor). We give sufficient conditions for a functor to be a p.i.c.-functor. In particular, any finitary normal functor is a p.i.c.-functor.

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

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 ...

Completeness for the coalgebraic cover modality [PDF]
Logical Methods in Computer Science, 2012 We study the finitary version of the coalgebraic logic introduced by L. Moss. The syntax of this logic, which is introduced uniformly with respect to a coalgebraic type functor, required to preserve weak pullbacks, extends that of classical propositional

Coinduction functor in representation stability theory [PDF]
Journal of the London Mathematical Society, 2015 We study the coinduction functor on the category of FI‐modules and its variants. Using the coinduction functor, we give new proofs of (generalizations of) various results on homological properties of FI‐modules.

Singular functors and realization functors
Indagationes Mathematicae (Proceedings), 1984 AbstractIn [6] Quillen showed that the singular functor and the realization functor have certain properties which imply the equivalence of the weak homotopy theory of topological spaces with the homotopy theory of simplicial sets. The aim of this note is to generalize this result and to show that one can, in essentially the same manner, establish the ...
