Projective curves, hyperplane sections and associated webs
Le Matematiche, 2014 An integral and non-degenerate curve $C\subset \mathbb {P}^r$ is said to be ordinary (Gruson, Hantout and Lehmann) if if the general hyperplane section $H\cap C$ of $H$ is of maximal rank in $H$.

Balanced generalized weighing matrices and their applications
Le Matematiche, 2004 Balanced generalized weighing matrices include well-known classical combinatorial objects such as Hadamard matrices and conference matrices; moreover, particular classes of BGW -matrices are equivalent to certain relative difference sets.

Asymptotics for the greatest zeros of solutions of a particular O.D.E.
Le Matematiche, 1994 This paper deals with the Liouville-Stekeloff method for approximating solutions of homogeneous linear ODE and a general result due to Tricomi which provides estimates for the zeros of functions by means of the knowledge of an asymptotic representation ...

ALPES: an advanced logic programming environment
Le Matematiche, 1988 This paper introduces a software programming environment for an extended Prolog language, called ALPES. The purpose of ALPES is to enable a logic programming paradigm to become a software engineering tool to design, develop and prototype traditional ...

Existence and uniqueness of solutions for fourth-order boundary-value problems in Banach spaces
Electronic Journal of Differential Equations, 2009 This article concerns the fourth-order boundary-value problem $$displaylines{ x^{(4)}(t)=f(t,x(t),x''(t)),quad tin (0,1),cr x(0)=x(1)=x''(0)=x''(1)=heta, }$$ in a Banach space. We present some spectral conditions, on the nonlinearity $f(t,u,v)$, to
