ABOUT THE AUTHOR
Carlos Isnard
He obtained his PhD degree in 1972 at the University of Chicago and developed his academic activities entirely at IMPA, since 1964. He focused his research on the topological degree theory, the theory of catastrophes, and optimization.
During his career he gave special attention to the teaching, leaving a deep impression in the formation of countless students. He knew like no one else how to make fun of human vanities without, however, being offensive. He was funny, tolerant and peaceful, he was a typical “carioca”, a character in extinction nowadays.
