Miroslav Fiedler was born on April 7, 1926, and died on November 20, 2015.
He was a Czech mathematician known for his contributions to linear algebra, graph theory and algebraic graph theory.
Miroslav article, “Algebraic Connectivity of Graphs”, published in the Czechoslovak Math Journal in 1973, established the use of the eigenvalues of the Laplacian matrix of a graph to create tools for measuring algebraic connectivity in algebraic graph theory.
Since then, this structure has become essential to large areas of research in flocking, distributed control, clustering and image segmentation.
Miroslav passed away at age 89 in November 2015.
