CAA: Padova-Verona research group on
"Constructive Approximation and Applications"

We work in the field of Constructive Approximation and Applications in a broad sense, with
a special interest in the study and implementation of effective approximation algorithms,
and in the production of reliable numerical software. Our main interests are presently in

Publications      Software      Workshops & Proceedings    


research programs:    the Padua Points       Discrete Extremal Sets

           Hyperinterpolation in d-cubes       Interpolation by RBF

                Dolomites Research Notes on Approximation

Graduate collaborators:
Roberto Montagna (Ph.D. student in Computing Sciences, East Anglia)

Contacts:    Stefano De Marchi       Marco Vianello

We collaborate in a research project (2009-2010, grant 38000 euros) on
Interpolation and Extrapolation: new algorithms and applications
coordinated by Michela Redivo Zaglia (Padova).

Moreover, we have a research project on
Multivariate approximation: theory, algorithms and applications
with the groups coordinated by G. Allasia (Torino) and F. Costabile (Cosenza).

We also work within the NumLab (Numerical Applications Laboratory - University of Padova).
