22nd mathematical hike - April 27th 2019 PDF Print

Dear Friends of Hikes and Mathematics,

You are cordially invited to the 22nd mathematical hike. It will take place on April 27th.

Start at 08:31 at the train stop Hradčany (near Tišnov).

We plan a nice april hike no matter the weather. It's about 19.2 km long. We will go south following a blue path to Veverská Bítýška (you can end the hike there (it is 8 km), if you prefer so), then continue through the hill Trnůvka to Bystrc (probably to tram stop Přístaviště).

Looking forward to seeing you there,

Jonatan Kolegar a Jana Bartoňová, organizers,
Jan Slovák, Director of the Department of Mathematics and Statistics

Agreeable and topologically agreeable abelian categoreies

In the category of modules over an associative ring, there is a notion of a summable family of morphisms between a given pair of objects. The sum of such an (infinite) family of morphisms is well-defined.
In fact, there is a natural topology on the group of morphisms between two modules, and the summable families are simply the families of morphisms converging to zero in this topology. Generalizing to additive categories, one comes to the definition of an agreeable additive category, which was suggested in a 1973 unpublished manuscript of A.L.S. Corner, and to a more narrow class of topologically agreeable categories.
All Grothendieck abelian categories are agreeable, and all nearly finitely presentable Grothendieck categories are topologically agreeable; but nondiscrete spectral Grothendieck abelian categories are not topologically agreeable.
