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.</span></font></span><span style="color:rgb(0,0,0)"><font size="2"><span style="font-family:arial,sans-serif"><br></span></font></span></div><div><span style="color:rgb(0,0,0)"><font size="2"><span style="font-family:arial,sans-serif">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.</span></font></span><span style="color:rgb(0,0,0)"><font size="2"><span style="font-family:arial,sans-serif"></span></font></span></div>
