We make explicit the exponential bound on the degrees of the polynomials appearing in the Effective Quillen-Suslin Theorem, and apply it jointly with the Hilbert-Burch Theorem to show that the syzygy module of a sequence of $m$ polynomials in $n$ var

Given a commutative local ring $(R,\mathfrak m)$ and an ideal $I$ of $R$, a family of quotients of the Rees algebra $R[It]$ has been recently studied as a unified approach to the Nagata's idealization and the amalgamated duplication and as a way to c

Resolution of singularities in algebraic varieties has been a topic of interest in commutative algebra and algebraic geometry during the last decades. Altough we have a theory of resolution of singularities for rings of characteristic zero, the case

We present a product formula for the initial parts of the sparse resultant associated to an arbitrary family of supports, generalising a previous result by Sturmfels. This allows to compute the homogeneities and degrees of the sparse resultant, and i

In this paper, to any subset $\mathcal{A} \subset \mathbb{Z}^{n}$ we explicitly associate a unique monomial projection $Y_{n,d_{\mathcal{A}}}$ of a Veronese variety, whose Hilbert function coincides with the cardinality of the $t$-fold sumsets $t\mat

Les F-singularitats són singularitats d'anells commutatius de característica primera relacionats amb l'endomorfisme de Frobenius. Per a poder-les estudiar, s'han introduit invariants numèrics com la multiplicitat de Hilbert-Kunz o la F-signatura,
