Homogeneous exact categories
Friday 14th August, 121pm, Carslaw 273.
In the present talk, we prove that a subcategory C of
the module category over a class of infinite dimensional algebras
R has almost split sequences and the strong homogeneous
property; that is, for each indecomposable module M in
C there is an almost split sequence starting and ending
at M. It is also proved that C is equivalent to
a related projective category L. Moreover, C is of
tame representation type if and only if L is semisimple,
and C is strictly void if and only if L is not
semisimple.
