Miroslav Fiedler
Miroslav Fiedler (April 7, 1926 – ) is a Czech mathematician known for his contributions to linear algebra, graph theory and algebraic graph theory.
His article, "Algebraic Connectivity of Graphs", from the Czechoslovak Math Journal in 1973, established the use of the eigenvalues of the Laplace 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.
