This volume of contributions pays tribute to the life and work of Djairo
Guedes de Figueiredo on the occasion of his 80th birthday. The articles
it contains were born out of the ICMC Summer Meeting on Differential
Equations - 2014 Chapter, also dedicated to de Figueiredo and held at
the Universidade de São Paulo at São Carlos, Brazil from February 3-7,
2014. The contributing authors represent a group of international
experts in the field and discuss recent trends and new directions in
nonlinear elliptic partial differential equations and systems.
Djairo Guedes de Figueiredo has had a very active scientific career,
publishing 29 monographs and over one hundred research articles. His
influence on Brazilian mathematics has made him one of the pillars of
the subject in that country. He had a major impact on the development of
analysis, especially in its application to nonlinear elliptic partial
differential equations and systems throughout the entire world. The
articles collected here pay tribute to him and his legacy and are
intended for graduate students and researchers in mathematics and
related areas who are interested in nonlinear elliptic partial
differential equations and systems.
