Model structure from small objects and left determined model structures

Abstract:
I'll present a way to characterize combinatorial weak model structures and left semi-model structures on a presentable category purely in terms of the cofibrations and trivial cofibrations between lambda-presentable objects (for some lambda).
As an application I'll present a generalization of Cisinski's theory of localizer to any locally presentable category instead of a topos. In particular it (partialy) answers the question posed by Rosicky and Tholen on the existence of left determined model structures.
If times permit (but probably not) I'll explain how this also allows to construct a "(pseudo) model category of model categories".

Call for research positions in Algebra at the Department of Mathematics and Statistics, Masaryk University

The Department of Mathematics and Statistics at Masaryk University invites applications for research positions commencing during the second half of the year 2019 at a date depending on mutual agreement.

The positions are initially for one year with a possibility of extension.

Applications will be considered in the area of algebra, with an emphasis on category theory.

The candidates must be recent PhD's and should submit a letter of application accompanied by a CV, list of publications and an outline of their research project to Martin Kolář ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it ) not later than April 30, 2019.

They should also arrange for at least 2 letters of recommendation (one can be from a Czech mathematician) to be mailed directly to This e-mail address is being protected from spambots. You need JavaScript enabled to view it before April 30, 2019.

The successful applicants will be notified as soon as possible but not later than May 31, 2019.
