Leonardo e il Novecento: dai futuristi alle mostre leonardesche
No full textIl saggio in catalogo illustra la sezione 8 della mostra "Leonardo di carta in carta. La costruzione del mito fra Ottocento e Novecento", a cura di S. Alessandri, M. Ceriana, S. Mammana (comitato scientifico: S. Alessandri, F. Barbagli, M. Ceriana, D. Colombo, S. Mammana, F. Tognoni, A. Tura, F. Valli, C. Vecce), tenutasi alla Biblioteca Nazionale Centrale di Firenze (BNCF) dal 5 dicembre 2019 al 14 marzo 2020. La sezione della mostra e il saggio sono dedicati a una breve rassegna dello sviluppo del mito di Leonardo a Vinci nei primi decenni del Novecento: dalla irrisione del mito della Gioconda fatto da artisti come Malevic, Duchamp, Picabia, Eluard, Leger e dai futuristi, che, però consideravano il maestro rinascimentale un modello di riferimento, all'influenza esercitata su Balla, Carrà, Fontana, fino alla sequenza di mostre che hanno sancito la definizione del mito di Leonardo scienziato, genio precursore e universale, fatto proprio dalla propaganda fascista, soprattutto con la Mostra Leonardesca del 1939 al Palazzo dell'Arte di Milano.The essay of the catalogue presents the section no. 8 of the exhibition "Leonardo di carta in carta. La costruzione del mito fra Ottocento e Novecento", ed. by S. Alessandri, M. Ceriana, S. Mammana (Scientifi Committee: S. Alessandri, F. Barbagli, M. Ceriana, D. Colombo, S. Mammana, F. Tognoni, A. Tura, F. Valli, C. Vecce), held at Biblioteca Nazionale Centrale in Firenze (BNCF) from December 5 2019 to March 14 2020. The exhibition section and the essay are dedicated to a short portrayal of the development of the myth of Leonardo da Vinci in earlier Twentieth-Century: the derision of myth of Gioconda by artists such as Malevic, Duchamp, Picabia, Eluard, Leger, and by futurists, who, anyway, considered him a model, as well as the influence on Balla, Carrà, and Fontana; moreover the sequence of shows dedicated to Leonardo “scientist”, pioneer and all-round genius, used by propaganda of Fascism, above all thanks to exhibition Leonardesca, held at Palazzo dell’Arte in Milan in 1939
Global Attractors of Non-autonomous Difference Equations
No full textThe article is devoted to the study of global attractors of quasi-linear non-autonomous difference equations, in particular we give the conditions for the existence of a compact global attractor. The obtained results are applied to the study of a triangular economic growth model recently developed by Brianzoni S., Mammana C. and Michetti E.Global attractors,Solow growth model,CGE,quasi-linear non-autonomous,difference equations,Endogenous population growth
A tetrahedron to model e-learning Mathematics
No full textIn this paper we introduce a model to 'read' the impact of e-learning technologies on the teaching/learning process, usually interpreted through the “didactical triangle” - knowledge, student, teacher (Chevallard, 1985). The idea we present here starts increasing the number of actors -that are author (A), student/s (S), tutor (T), mathematical knowledge (M) - and makes the model to become three-dimensional, passing from a triangle to a tetrahedron. The mediation of technology is represented by a sphere inscribed in the tetrahedron. The tangent point of the sphere with each face of the tetrahedron allows us to look at the relations among the three actors (the vertices of the face) in the e-learning environment and then how they can be transmitted /fostered/created by the new technological tools
