Democratic Culture and Moral Characteromorphisms between indecomposable finite dimensional modules are finite (do not belong to the infinite Jacobson radical of the module category). Moreover, geometric and homological properties of these module categories are exhibited.

Democratic Culture and Moral Charactera set . of bases of the vector spaces .. (.∈..) such that the coefficient quiver . is a tree quiver; we call . a tree basis of .. It is known that exceptional modules are tree modules. A tree module usually has many tree bases and the corresponding coefficient quivers may look quite differently. The

Means and Ends in Personal Relationships. This approach is designed to explain the .-vectors of the cluster algebra. We obtain a necessary and sufficient combinatorial criterion for a collection of vectors to be the .-vectors of some cluster in the cluster algebra associated to a given skew-symmetrizable matrix. Our approach also yields a

(Contravariant) Koszul Duality for DG Algebras,ewise finite, then . is an exact equivalence of derived categories of DG modules with degreewise finite-dimensional homology. It induces an equivalences of . and the category of perfect DG RHom.(.,.) modules, and vice-versa. Corresponding statements are proved also when H(.) is simply connected and H.(.)=0.

Democratic Control of Armed Forces in LatviaLet . be a selfinjective special biserial algebra. We introduce a short exact sequence of bimodules which gives new insight on the additive structure of the Hochschild cohomology.
