Hopf-type estimates for solutions to Hamilton-Jacobi equations with concave-convex initial data
Electronic Journal of Differential Equations, 2003 We consider the Cauchy problem for the Hamilton-Jacobi equations with concave-convex initial data. A Hopf-type formula for global Lipschitz solutions and estimates for viscosity solutions of this problem are obtained using techniques of multifunctions ...

Quadratic forms as Lyapunov functions in the study of stability of solutions to difference equations
Electronic Journal of Differential Equations, 2011 A system of linear autonomous difference equations $x(n+1)=Ax(n)$ is considered, where $xin mathbb{R}^k$, $A$ is a real nonsingular $kimes k$ matrix.

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 ...
