Scientific results

Ginestra Bianconi’s research focuses on Network Theory,Applied Mathematics and Statistical Mechanics applied to Complex Systems. Networks describe the rich underlying structure of Complex Systems and are formed by the set of elements of the system (nodes) and the interactions among them (links). The most prominent examples of complex networks include the brain and social networks.

Ginestra Bianconi’s research activity in Network Theory is motivated by the urgent need to develop theoretical approaches that address the challenges posed by the complexity of real networks using innovative approaches at the frontier between Applied Mathematics and Statistical Mechanics. Among her most relevant results we mention the Bianconi-Barabási model. This model explains how networks such as the Internet or the World-Wide-Web evolve by establishing a map between the network evolution and the Bose-Einstein condensation, a quantum phenomenon occurring in a gas of Bose particles. Another notable research line of Ginestra Bianconi is the formulation of an information theory of networks based on entropy of network ensembles that can be used to solve inference problems. Recently the research activity of Ginestra Bianconi has focused on multilayer networks that describe systems formed by several interacting networks and on network geometry. Additonally, Ginestra Bianconi has several interdisciplinary collaborations with scientists in neuroscience and informatics and with economists.

Position/Role

Full Professor of Numerical Analysis at the University of Pavia

Professional career

After graduating in Mathematics at the University of Pavia in 1970 she has been fellow first, and then Researcher of C.N.R. at the Istituto di Analisi Numerica in Pavia (now IMATI-CNR) from 1973 to 1990.  Since 1990 she is Full Professor of Numerical Analysis, at the Faculty of Science of the University of Genova until 1993, and then at the Engineering Faculty of the University of Pavia.

Scientific results

The field of interest of Luisa Donatella Marini is, generally speaking, the analysis of numerical schemes for the solution of elliptic partial differential equations (of second and fourth order) by means of different kinds of finite element methods: conforming, non-conforming, hybrid, mixed, and equilibrium. More specifically, she applied finite element techniques for the treatment of problems coming from various applications: semiconductor device simulation, electromagnetism, fluid-dynamics, structural mechanics. Particular emphasis was given to the approximation of non-coercive problems, which lead to develop various techniques for stabilizing Galerkin formulations, for applications to domain decomposition methods with non-matching grids, and to advection dominated problems. In the last decade she was particularly interested in developing and analyzing schemes based on Discontinuous Galerkin methods, for the discretization of various applied problems, such as Darcy flows, advection-diffusion problems, and Reissner-Mindlin model for plate problems. The more recent production is devoted to a new technique, the Virtual Element Method, for the discretization of Pde's  with applications.

Scientific results

She is currently responsible for a research group that is interested in the study of partial differential, linear and quasilinear equations and climate change and their impact.

  With her team he defined an index that makes it possible to easily calculate the territorial effect of sensitivity to desertification in order to exceed the international protocol limit "Mediterranean Mediterranean Desertification And Land Use European" (MEDALUS), which does not provide an estimate of sensitivity to the desertification of a territorial area (municipal, provincial, regional, hydrographic area) through a single value. This index has significant advantages, because it produces effective rankings, with the consequent possibility of processing comparative data in relation to different time periods.

Within the scope of this research in mathematics applied to the protection of the environment, the effects of the impact of the transport of Saharan dust on particulate matter (PM10) are studied.
