Počátky teorie matic v českých zemích (a jejich ohlasy) / Origins of Matrix Theory in Czech Lands (and the responses to them)

Štěpánová, Martina January 2013 (has links)
In the 1880s and early 1890s, the Prague mathematician Eduard Weyr published his important results in matrix theory. His works represented the only significant contribution to matrix theory by Czech mathematicians in many decades that followed. Although Eduard Weyr was one of the few European mathematicians acquainted with matrix theory and working in it at that time, his results did not gain recognition for about a century. Eduard Weyr discovered the Weyr characteristic, which is a dual sequence to the better known Segre characteristic, and also the so-called typical form. This canonical form of a matrix is nowadays called the Weyr canonical form. It is permutationally similar to the commonly used Jordan canonical form of the same matrix and it outperforms the Jordan canonical form in some mathematical situations. The Weyr canonical form has become much better known in the last few years and even a monograph dedicated to this topic was published in 2011.

Masarykova universita a rozvoj statistiky v meziválečném období / Masaryk University and the development of statistics in the interwar period

Sedláčková, Andrea January 2009 (has links)
The aim of my work, after collecting and studying the available literature, is to describe a long and difficult development of universities in Moravia, which resulted in the creation of the Masaryk University in Brno. Trying to summarize and analyze the life work of five prominent personalities who are closely connected with the history of the Masaryk University and its activities, not a few have contributed to the development of statistics in the interwar period.

Histoire du théorème de Jordan de la décomposition matricielle (1870-1930).<br />Formes de représentation et méthodes de décomposition.

Brechenmacher, Frederic 09 March 2006 (has links) (PDF)
L'histoire du théorème de Jordan est abordée sous l'angle d'une question d'identité posée sur la période qui sépare la date de 1870 et l'énoncé par Camille Jordan d'une forme canonique des substitutions linéaires des années trente du vingtième siècle au cours desquelles le théorème de Jordan de la décomposition matricielle acquiert une place centrale dans la théorie des matrices canoniques. A partir d'un moment historique de référence, la controverse entre Jordan et Kronecker de 1874, le théorème de Jordan permet de jeter un regard original sur l'histoire de la période 1870-1930 en suivant le rôle joué par des savoirs tacites, des idéaux et des pratiques propres à des réseaux et des communautés. Ce regard permet notamment de mettre en évidence la dynamique d'une tension entre formes canoniques et invariants dans l'évolution de la signification de la notion de forme en mathématiques et contribue à l'histoire de l'algèbre linéaire en décrivant le rôle joué par une méthode de décomposition indissociable d'un mode particulier de représentation : la décomposition matricielle.
