34th mathematical hike  11th of December 2021 


Dear Friends of Hikes and Mathematics,
The 34th mathematical hike is planned on the 11th of December. Start at 9:33 at the "Kamenolom" stop. (49.2218894N, 16.5368919E). The hike is about 15 km long, we will go through the "Podkomorský" forest to the dam. We invite you also to the traditional mathematical carolsinging. (lyrics in czech, though)
Consider your attendance accordingly with the covid situation. The government does not restrict organizing hikes.
All information and photos can be found at https://conference.math.muni.cz/vylety/. (in CZ) Looking forward to see you. Jana Bartoňová and Jonatan Kolegar, organizers Jan Slovák, Director of the Department of Mathematics and Statistics

Higher theories and monads
Abstract: We extend Bourke and Garner's idempotent adjunction between monads and pretheories to the framework of $\infty$categories, and exploit this to prove many classical theorems about monads in the $\infty$categorical setting. Amongst other things, we prove that the category of algebras for an accessible monad on a locally presentable $\infty$ category is locally presentable. We also apply the result to construct examples of $\infty$categorical monads from pretheories.

The nerve of a relative monad
Abstract: In this talk we will consider an embedding of monads into double categories, which sends a monad P to its (concrete) double category of Pembeddings (also called P split monos), as well as generalizations of this embedding the setting of (wellbehaved) relative monads. By considering a more general notion of monad morphism (motivated by the relative setting), we will understand this embedding as a fully faithful nerve which exhibits the terminal monad as 'dense' with respect to these more general morphisms. We will then give two applications of this construction. Firstly, we will give another approach by which one arrives at the “decagon type” axioms of last time, and secondly we will give a simpler proof of the reduced form of pseudodistributive laws involving laxidempotent pseudomonads. Note that some parts are a work in progress.
