Let R = S/I where S = k[T_1, . . . , T_n] and I is a homogeneous ideal in S. The acyclic closure R<Y> of k over R is a DG algebra resolution obtained by means of Tate’s process of adjoining variables to kill cycles. In a similar way one can obtain t... see more

Let K be a field, E the exterior algebra of a n--dimensional K-vector space V. We study projective and injective resolutions over E. More precisely, given a category M of finitely generated Z-graded left and right E-modules, we give upper bounds for the g... see more

We describe an algorithm that allows to compute a minimal resolution of the Steenrod algebra. The algorithm has built-in knowledge about vanishing lines for the cohomology of sub Hopf algebras of the Steenrod algebra which makes it both faster and more ec... see more

We propose a canonical resolution of singularities of a triple covering X of algebraic surfaces Y when X is normal and Y is smooth.

Determining the potential bioavailability of heavy metals, evaluating according to adapted regulations is essential to efficiently conserve our coastal and estuarine waters. In this study, it is aimed to determine the industrial pollution and various othe... see more

STRENGTHENING TEACHER PEDAGOGICAL COMPETENCIES THROUGH THE USE OF DYNAMIC GEOMETRY SOFTWARE IN MATHEMATICS LEARNING. The selection of strategies, methods, models, and media of appropriate mathematics learning is a form of implementation of a teacher's ped... see more

In this article we present the results of the evaluation phase of a training intervention with primary education prospective teachers on the subject of proportionality. The focus is on developing the epistemic and cognitive analysis competence of mathemat... see more
