Marsico, G. (2017). Vygotsky: The question of psychological synthesis. In W-M., Roth and A., Jornet. Understanding Educational Psychology. A late Vygotskian, Spinozist approach. Cultural Psychology of Education, 3, (pp. v-vi), Cham, Switzerland: Springer;
No full textIn the contemporary academic world, dominated by “ready-made receipts” for explaining psychological processes, Roth and Jornet took upon themeselves the hard task of revising Vygotsky legacy on the basis of Spinoza’s relevance in his thinking. The authors focused on the Russian scholar’s “later years”, almost still unknown worldwide to both the large audience and serious specialists in educational psychology and adjacent areas. The book greatly contributes to the consolidation of a cultural psychology’s perspective in education to restore the relevance of a general theoretical elaboration against the flattening of present-day educational psychology

A simple proof of Kotake-Narasimhan theorem in some classes of ultradifferentiable functions
No full text[EN] We give a simple proof of a general theorem of Kotake-Narasimhan for elliptic operators in the setting of ultradifferentiable functions in the sense of Braun, Meise and Taylor. We follow the ideas of Komatsu. Based on an example of Metivier, we also show that the ellipticity is a necessary condition for the theorem to be true.C. Boiti and D.

A characterization of the wave front set defined by the iterates of an operator with constant coefficients
No full text[EN] We characterize the wave front set WF*P (u) with respect to the iterates of a linear partial differential operator with constant coefficients of a classical distribution u is an element of D '(Omega), Omega an open subset in R-n. We use recent Paley-Wiener theorems for generalized ultradifferentiable classes in the sense of Braun, Meise and Taylor. We also give several examples and applications to the regularity of operators with variable coefficients and constant strength. Finally, we construct a distribution with prescribed wave front set of this type.The authors were partially supported by FAR2011 (Universita di Ferrara), "Fondi per le necessita di base della ricerca" 2012 and 2013 (Universita di Ferrara) and the INDAM-GNAMPA Project 2014 "Equazioni Differenziali a Derivate Parziali di Evoluzione e Stocastiche" The research of the second author was partially supported by MINECO of Spain, Project MTM2013-43540-P.Boiti, C.; Jornet Casanova, D.

Regularity of partial differential operators in ultradifferentiable spaces and Wigner type transforms
No full text[EN] We study the behaviour of linear partial differential operators with polynomial coefficients via a Wigner type transform. In particular, we obtain some results of regularity in the Schwartz space \Sch and in the space \Sch_\omega as introduced by Bj\"orck for weight functions . Several examples are discussed in this new setting.The authors have been partially supported by the INdAM-GNAMPA Project 2015 "Equazioni Differenziali a Derivate Parziali di Evoluzione e Stocastiche" and by FAR 2011 (University of Ferrara).

A Note on Supercyclic Operators in Locally Convex Spaces
No full text[EN] We treat some questions related to supercyclicity of continuous linear operators when acting in locally convex spaces. We extend results of Ansari and Bourdon and consider doubly power bounded operators in this general setting. Some examples are given.We are indebted to Prof. Jose Bonet for his helpful suggestions on the topic of this paper.
