    Analytic Functors and Weak Pullbacks, accepted for publication

  • Original language description

    For accessible set-functors it is well-known that weak preservation of limits is equivalent to representability, and weak preservation of connected limits to familial representability. In contrast, preservation of weak wide pullbacks is equivalent to being a coproduct of quotients of hom-functors modulo groups of automorphisms. For finitary functors this was proved by Andre Joyal who called these functors analytic. We introduce a generalization of Joyal's concept from endofunctors of $\Set$ to endofunctors of a symmetric monoidal category.

    Analytické funktory a slabé pullbacky

  • Czech description

    Je známo, ľe slabé zachovávání limit je pro akcesibilní mnoľinové funktory ekvivalentní representabilitě, a ľe slabé zachovávání souvislých limit je ekvivalentní familiální representabilitě. Na druhé straně, zachovávání slabých ąirokých pullbacků je ekvivalentní tomu, ľe funktor lze vyjádřit jakoľto koprodukt hom-funktorů modulo grupy automorfismů. Pro finitární funktory toto dokázal Andre Joyal a nazval takové funktory analytické. Zavádíme zobecnění Joyalova pojmu z endofunktorů $\Set$ na endofunktorysymetrické monoidální kategorie.
