In the plane, this mathematician's namesake measure involves finding the greatest lower bound of the areas of the coverings of a given set, where a covering consists of a finite union of rectangles. One result named for this mathematician and Hölder follows from Zassenhaus's Lemma via Schreier's Refinement Theorem and states that any two composition series in a group are isomorphic. Any matrix with coefficients from an algebraically closed field can be rewritten in terms of blocks containing a single eigenvalue on the main diagonal and ones on the superdiagonal, a block form name after this man. Another result of his states that any closed curve divides the plane into an inside and an outside. For 10 points, identify this French mathematician, namesake of a "normal" or "canonical" form of a matrix, as well as a curve theorem.
