We shall study the existence of almost split sequences in tri-exactcategories, that is, extension-closed subcategories of triangulated categories.Our results unify and extend the existence theorems for almost split sequencesin abelian categories and exact categories (that is, extension-closedsubcategories of abelian categories), and those for almost split triangles intriangulated categories. As applications, we shall obtain some new results onthe existence of almost split sequences in the derived categories of allmodules over an algebra with a unity or a locally finite dimensional algebragiven by a quiver with relations.
