A C-free approach to linear ODEs with constant coefficients

2012

The purpose of this paper is to present an alternative way of establishing the general solution of the equation x''(t)+x(t)=0 without relying on complex numbers. Our method can be extended to the corresponding non-homogeneous equation and, more generally, to higher-order equations.

Linear dynamics induced by odometers

2022

Weighted shifts are an important concrete class of operators in linear dynamics. In particular, they are an essential tool in distinguishing variety dynamical properties. Recently, a systematic study of dynamical properties of composition operators on $L^p$ spaces has been initiated. This class of operators includes weighted shifts and also allows flexibility in construction of other concrete examples. In this article, we study one such concrete class of operators, namely composition operators induced by measures on odometers. In particular, we study measures on odometers which induce mixing and transitive linear operators on $L^p$ spaces.

Local uniqueness of the solutions for a singularly perturbed nonlinear nonautonomous transmission problem

2020

Abstract We consider the Laplace equation in a domain of R n , n ≥ 3 , with a small inclusion of size ϵ . On the boundary of the inclusion we define a nonlinear nonautonomous transmission condition. For ϵ small enough one can prove that the problem has solutions. In this paper, we study the local uniqueness of such solutions.

Inversion formulae for the integral transform on a locally compact zero-dimensional group

2009

Abstract Generalized inversion formulae for multiplicative integral transform with a kernel defined by characters of a locally compact zero-dimensional abelian group are obtained using a Kurzweil-Henstock type integral.

Integration by parts for the Lr Henstock-Kurzweil integral

2015

Musial and Sagher [4] described a Henstock-Kurzweil type integral that integrates Lr-derivatives. In this article, we develop a product rule for the Lr-derivative and then an integration by parts formula.

Il Moderno e la Provincia : riflessioni grafiche su uno spazio mai nato: la Casa del Balilla di Luigi Moretti a Bitonto

2020

Luigi Moretti è stato indubbiamente uno dei più grandi architetti italiani del ‘900. La sua fortuna iniziò durante il ventennio fascista, quando progettò diversi edifici per l’Opera Nazionale Balilla, tra cui la sede di Bitonto, edificio non realizzato di dimensioni contenute, a cui la storiografia ha dedicato pochissimo spazio, derubricandolo forse ad un’esperienza di secondo piano nella carriera dell’architetto romano. Ma è davvero così? La località, centro minore (ricco di storia e tradizioni) nella provincia del Sud Italia, può avere influenzato le scelte progettuali? In che modo? Si può parlare di un progetto chiaro dello spazio? L’eventuale confronto con le altre Case del Balilla cost…

La ricerca del value for money nei progetti di opere pubbliche

2012

The search of value for money in the field of public works is now an indispensable element to improve the relationship cost effectiveness of all investments that involve the use of resources of the communities. The article, based on the European Economic situation analyzes the evolution of evaluative methodologies in Italy and Europe showing, through some case studies, the elements that contribute most to the success of the evaluation both in terms economic and social benefits.
