Localization of the K-Theory of Polynomial Extensions.
Localization of tight closure and modules of finite phantom projective dimension.
Locally compact modules over compact rings
Sia un anello compatto e sia un -modulo localmente compatto. Le dimostrazioni note che è linearmente topologizzato sembrano alquanto involute ed usano risultati profondi della teoria dei gruppi Abeliani localmente compatti nonché il Teorema di Kaplansky che asserisce che è linearmente topologizzato. In questa Nota, poggiando sul Teorema di Peter-Weyl, viene esposta una dimostrazione semplice e diretta, della quale il Teorema di Kaplansky è corollario.
Locally complete intersection homomorphisms and a conjecture of Quillen on the vanishing of cotangent homology.
Locally finite iterative higher derivations on k[x,y]
We give a new proof of Miyanishi's theorem on the classification of the additive group scheme actions on the affine plane.
Locally Nilpotent Monomial Derivations
We prove that every locally nilpotent monomial k-derivation of k[X₁,...,Xₙ] is triangular, whenever k is a ring of characteristic zero. A method of testing monomial k-derivations for local nilpotency is also presented.
Locally Polynomial Algebras are Symmetrie Algebras
Loewy coincident algebra and -3 associated graded algebra
We prove that an associated graded algebra of a finite dimensional algebra is (= selfinjective) if and only if is and Loewy coincident. Here is said to be Loewy coincident if, for every primitive idempotent , the upper Loewy series and the lower Loewy series of and coincide. -3 algebras are an important generalization of algebras; note that Auslander algebras form a special class of these algebras. We prove that for a Loewy coincident algebra , the associated graded algebra...
