*Konuşmacı:* Septimiu Crivei
*Konuşma Başlığı:* Maximal Exact Structures on Additive Categories
<http://www.turkmath.org/beta/seminer.php?id_seminer=3022>
*Konuşma Özeti:* Quillen exact categories have recently reappeared into the
mainstream due to some new applications to algebraic K-theory, model
structures, approximation theory or functional analysis. They provide a
suitable setting for developing homological algebra beyond abelian
categories, as is often the case in the above settings.
Every additive category has an obvious smallest exact structure given by
the split exact sequences. It is natural to wonder whether there exists,
and then which is, the greatest exact structure on an arbitrary additive
category. We review known results for preabelian, weakly idempotent
complete and additive categories, and we present some steps towards its
description.
