Abstract
Isogeometric analysis (IGA) emerged as a technology bridging Computer Aided Geometric Design (CAGD), most commonly based on Non-Uniform Rational B-Splines (NURBS) surfaces, and engineering analysis.
In finite element and boundary element isogeometric methods (FE-IGA and IGA-BEM), the NURBS basis functions that describe the geometry define also the approximation spaces. The resulting approximation schemes can be used very effectively as a high-fidelity approximation in Reduced Basis (RB) methods, providing a tool for the rapid and reliable evaluation of PDE systems characterized by complex geometrical features.
After a brief overview of the various techniques, I will present an application of this technology, where we address the simulation of potential flows past airfoils, parametrized with respect to the angle of attack and the NACA number identifying their shape, to optimize in real time the trimming of the rigid sail of a catamaran, using RB IGA-BEM.

Transition fronts for monostable reaction-diffusion equations

Abstract
The standard notions of reaction-di usion traveling fronts can be viewed as examples of generalized transition fronts. These notions involve uniform limits, with respect to the geodesic distance, to a family of hypersurfaces which are parametrized by time. The existence of transition fronts has been proved in various contexts where the standard notions of fronts make no longer sense. Even for homogeneous equations, fronts with varying speeds are known to exist. In this talk, I will rst review the various notions of standard and transition fronts and I will then report on some recent existence results and qualitative properties of transition fronts for monostable homogeneous and heterogeneous one-dimensional equations. I will also discuss their asymptotic past and future speeds. The talk is based on some joint works with Luca Rossi.
