Habilitation colloquium of Dr. Roswitha Rissner
On February 19, 2024, Dr. Roswitha Rissner held the habilitation colloquium entitled “On the algebraic and arithmetic structure of commutative rings”.
In her lecture, she began by describing the emergence of modern algebra through number theory and geometry. From Fermat’s last theorem and Gabriel Lame’s failed attempt to prove it, to Richard Dedekind and the introduction of the abstract objects of rings and the algebraic description of Riemann surfaces, to Emmy Noether, who laid the foundations of modern algebra.
