    Dense Morphisms of Monads

  • Original language description

    Given an arbitrary locally finitely presentable category K and finitary monads T and S on K, we characterize monad morphisms alpha: S --> T with the property that the induced functor alpha_*: K^T --> K^S between the categories of Eilenberg-Moore algebrasis fully faithful. We call such monad morphisms dense and give a characterization of them in the spirit of Beth's definability theorem. We also give a characterization in terms of epimorphic property of alpha and clarify the connection between various notions of epimorphisms between monads.

    Husté morfismy monád

  • Czech description

    Pro libovolnou lokálně konečně presentovanou kategorii K a finitární monády T a S charakterizujeme ty morfismy monád alpha: S --> T s vlastností, že indukovaný funktor alpha_*: K^T --> K^S mezi kategoriemi Eilenberg-Mooreových algeber je fully faithful.Takovým morfismům monád říkáme husté a podáváme jejich charakterizaci v duchu Bethovy věty o definovatelnosti. Podáváme též charakterizaci pomocí epimorfní vlastnosti alphy a vysvětlujeme souvislosti mezi různými pojmy epimorfismů monád.
