On a problem of P. Hall for Engel words II
No full textThe present paper is related to some recent studies in Abdollahi and Russo [‘On a problem of P. Hall for Engel words’, Arch. Math. (Basel) (2011), 407–412] and Fernández-Alcober et al. [‘A note on conciseness of Engel words’, Comm. Algebra (2012), 2570–2576] on the position of the --Engel marginal subgroup of a group , when . Describing the size of for , we show some generalisations of classical results on the partial margins of and .

Varieties with quadratic entry locus. II
No full textWe continue the study, begun in [F. Russo, Varieties with quadratic entry locus. I, Preprint (2006), math. AG/0701889] , of secant defective manifolds having simple entry loci. We prove that such manifolds are rational and describe them in terms of tangential projections. Using also the work of [P.Ionescu and F.Russo, Conic-connected manifolds, Preprint (2006), math. AG/0701885], their classification is reduced to the case of Fano manifolds of high index, whose Picard group is generated by the hyperplane section class. Conjecturally, the former should be linear sections of rational homogeneousmanifolds. We also provide evidence that the classification of linearly normal dual defective manifolds with Picard group generated by the hyperplane section should follow along the same lines. © 2008 Copyright Foundation Compositio Mathematica 2008
Design in the Digital Age. Technology, Nature, Culture
No full textDesign Culture is facing a renewed relationship between Technology and Environment, evolving from the vision of Nature
as unlimited storage of raw materials and energy, to another in which Nature is recognized as a finite heritage to synergistically
interact with. According to a such perspective, this seems to be the only possible vision to responsibly face the anthropogenic
environment, as well as the further crises , mainly the socio-economic ones, plagueing the planet (from climatic emergencies to migratory phenomena and social inequalities).
Moreover, the Design Culture has been for long undergoing deep transformations, determined by the increasingly diffusion of the digital (and somehow pervasive) technologies which introduce new paradigms, both cognitive and operative, within the traditional design thinking and its expressive methods. Design horizons have thus been widening their objectives and potentialities thanks to the rise of digital design approach, whose limits are still unknown. Therefore, the digital "revolution" is generating important changes in the dynamics of building production and processes, due to design has increasingly characterized by information input and the relationships between the elements that define its field of action.
The scenario described above allows to define a new epistemological field where the Technology in the digital age seems to play a crucial role in the relationship between Culture and Nature. By this purpose, it is necessary to start a critical reflection to take up the challenge subtended to the changes that are taking place at the present, and to re-interpretated some of the classical dichotomies underlying the Culture of contemporary design, such as material-immaterial, subject-object, real-virtual, local-global, possibility-responsibility, knowledge-information, representation-simulation. This involves a paradigm shift in the relation between Culture and Nature, that is now based on a new design concept that assumes change and uncertainty as epistemological assumptions. According to this perspective, the Technology of Architecture becomes a field of feasible possibilities able at generating new producion modalities, so building and living in harmony with the natural systems.
The book is therefore organized in three sections:
1_Technology and evolution of the eco-systemic approach to the design (ed. Marina Rigillo)
2_Technology and construction of a new material culture (ed. Sergio Russo Ermolli)
3_Technology and generation of innovative habitat (ed. Fabrizio Tucci)

Strong subgroup commutativity degree and some recent problems on the commuting probabilities of elements and subgroups
No full textWe show some results on the probability that a randomly picked pair of subgroups of a finite group satisfies . This notion of probability is related with the subgroup -commutativity degree in [D.E. Otera and F.G. Russo, Subgroup -commutativity degree of finite groups, Bull. Belgian Math. Soc. 19 (2012), 373–382]. Numerical inequalities will be illustrated, in order to find connections with the subgroup commutativity degree and with the commutativity degree of . On the other hand, the literature has known a significant growth in the last years and so we discuss a series of new open problems, which are arousing interest in the area. The presence of a large bibliography allows us to have a detailed overview of the status of knowledge on the topic
Prefazione a Aspetti e questioni multidisciplinari della democrazia paritaria dall'antichità ai nostri giorni
No full textLa prefazione presenta i contributi del volume collettaneo "Aspetti e questioni multidisciplinari della democrazia paritaria: lo spazio pubblico e privato dall’antichità ai nostri giorni" esito degli interventi presentati dai relatori all’omonimo ciclo di seminari coordinato dalla Fondazione Iotti di Roma e dal Dipartimento di Scienze politiche e relazioni internazionali dell’Università di Palermo, con il coinvolgimento di docenti dello stesso Ateneo. Inserito nell’ambito di un quadro di attività svolte grazie a un protocollo d’intesa siglato nel marzo del 2022, questo volume testimonia il valore della collaborazione tra istituzioni che desiderano offrire un contributo alla discussione sulla rappresentanza di genere, sullo sviluppo della democrazia e la riforma delle istituzioni, nella convinzione che le azioni di cambiamento richiedono l’attivazione di processi che non possono prescindere dalla sollecitazione, in particolare tra le nuove generazioni, a ‘riflettere’ per meglio comprendere la complessità della realtà e aprire nuovi spazi di dialogo fra le generazioni, in omaggio a un’idea di democrazia sostanziale sempre più moderna e inclusiva
