05021 Abstracts Collection – Mathematics, Algorithms, Proofs

Authors: Thierry Coquand, Henri Lombardi, and Marie-Françoise Roy

Published in: Dagstuhl Seminar Proceedings, Volume 5021, Mathematics, Algorithms, Proofs (2006)

Abstract
From 09.01.05 to 14.01.05, the Dagstuhl Seminar 05021 ``Mathematics, Algorithms, Proofs'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. LinkstFo extended abstracts or full papers are provided, if available.

Subdiscriminant of symmetric matrices are sums of squares

Authors: Marie-Françoise Roy

Published in: Dagstuhl Seminar Proceedings, Volume 5021, Mathematics, Algorithms, Proofs (2006)

Abstract
We present a very elementary algebraic proof providing an explicit sum of squares. This result generalizes a result on discriminants of symmetric matrices due to Ilyushechkin and proved also by P. Lax.
