The workshop on Mathematical Modelling and Mathematical Methods in Energy was held in COPEL Building, Curitiba, Brazil from 29 November to 1 December 2004 with more than 100 participants.
The scientific programme consisted of 20 invited talks and 20 contributed papers. All talks were well attended with deep discussions. The participants came from Brazil, Canada, China and U.S.A. The following mathematical modelling and methods applied in energy area such as petrol and electric energy were discussed: partial differential equations, singular value decomposition (SVD), eigenvalue problems, preconditioning techniques and optimization. All participants, especially people from energy engineering, recognized the importance of participation and collaboration with mathematicians for their researches. The present volume contains seven selected papers essentially devoted to numerical linear algebra with applications in energy area.
We thank the referees who helped us in doing the editorial work. Their efforts and suggestions made it possible to publish scientific papers with high quality. We appreciate the support of the Scientific Committee of the Workshop consisting of
