*didaktischer **Vortrag im Rahmen der Habilitation *

*Dr. Harald Grobner (Fakultät für Mathematik, Universität Wien): *

*"From triangles to modular forms -- from Fibonacci's "congrua" to 
Fermat's Last Theorem"*

**

/Abstract: In his book {\it Liber Quadratorum} (Book of Squares) from 
1225, Fibonacci studied 3-term arithmetic progressions of integral 
squares, i.e. triples of the form $(x^2-n, x^2, x^2+n)$ with both $x^2/

/\pm n$ being squares. More generally, allowing triples of squares of 
rational numbers, the question of which triples of that form 
(Fibonacci's "congrua") exist, is equivalent to asking which integers/

/$n$ can be written as the area of a right triangle with rational 
sides.As we will see, this at first sight maybe simple looking question, 
leads us directly to consider elliptic curves and their rational points. 
This, in/

/turn, is intimately linked to Fermat's Last Theorem and its proof by 
Wiles and Taylor./

/The passage from elliptic curves to Fermat's Last Theorem is provided 
by cuspidal modular forms. These are certain functions on the Siegel 
upper half-space, which might be viewed as the most classical instance/

/of what one would nowadays call an automorphic form. If time permits, 
we will shortly sketch the eminent role of automorphic formsin the 
Langlands Program, a program, which, from some perspective,/

/generalizes some ideas behind the proof of FLT./

//

/Der Vortrag [Dauer 60 Minuten] zu einem Thema eigener Wahl richtet/

/sich an Studierende, die das 3.te Studienjahr abgeschlossen haben. Dies/

/dient auch als Grundlage der zu erstellenden Gutachten bzgl. der/

/didaktischen Fähigkeiten des Kandidaten.///
