over the rationals has a conjectural extension to general number fields.
For example, over odd degree totally real fields, one knows how to
associate an elliptic curve to a weight 2 newform with integer Hecke
eigenvalues. Conversely, very recent work of Freitas, Hun and Siksek
show that over totally real fields, most elliptic curves are modular (in
fact, over real quadratic fields, "all" are modular).<br>
<br>
Beyond totally real fields, we are at a loss at associating elliptic
curves to weight 2 newforms. The best one can do is to "search" for the
elliptic curve. In joint work with X.Guitart (Essen) and M.Masdeu
(Warwick), we generalize Darmon's conjectural construction of algebraic
points on elliptic curves to general number fields and then use this
conjectural construction to analytically construct the elliptic curve
starting from a weight 2 newform over a general number field, under some
hypothesis. In the talk, I will start with a discussion of the first
paragraph and then will sketch our method.<br><br></div>Zaman: 25.12.2014 16:00<br>Yer: MSGSÜ, Bomonti Kampüsü (<a href="http://math.msgsu.edu.tr/iletisim.html" target="_blank">Harita</a>), Matematik Bölümü Seminer Odası<br><br>-------------------------------------------------<br><br>Konuşmacı: Haydar Göral (Université Lyon 1)<br><br></div><div>Başlık: Mann Property<br><br></div><div>Özet: In this talk we study the pair (K,G) where K is an algebraically
closed field and G is a multiplicative subgroup of K* with the Mann
property. The main examples of this property comes from number theory.
The reason of the naming like this is that H. Mann proved that the roots
of unity has the Mann property. The theory of the pair is axiomatised
by L. van den Dries and A. Günaydın and they prove that the pair (K,G) is stable. We first characterize the independence in the pair and this allows us to characterize the definable groups in (K,G).</div><div><br></div>Zaman: 26.12.2014 16:00<br><div>Yer: MSGSÜ, Bomonti Kampüsü (<a href="http://math.msgsu.edu.tr/iletisim.html" target="_blank">Harita</a>), Matematik Bölümü Seminer Odası<br><br><br></div></div>
