Rational Points on Curves
Hikmet Burak Özcan (DEU) Date&Time: 29/03/2019, 10:00 Place: B256 In this talk, after defining rational points on a curve we will address the problem of finding the rational points on curves. We will give a recipe in order to generate a new rational point from already known ones. After that we will introduce the notion ... Read more

The Second Invitation to Algebraic Number Theory

First, we will briefly recall what we did in the first talk. Then ... Read more

Probabilistic Methods in Number Theory
Doga Can Sertbaş, Cumhuriyet University Date and Time: 22/03/2019, 10:00 Place: B256 In 1947, Erdos gave a lower bound for the diagonal Ramsey numbers R(k,k). His proof contains purely probabilistic arguments where the original problem is not related to the probability theory. This pioneering work of Erdos gave rise to a new proof technique which ...

Knotted Strings in the plane
Neslihan Güğümcü, Technical University of Athens Date and Time: 15/03/2019, 10:00 Place: B256 Abstract: Planar curves have been studied since the time of Gauss. Gauss was one of the first to notice that they can be handled combinatorially by codes (named as Guass codes) that are strings of labels encoding self-intersections. Whitney classified all immersed ... Read more

Counting from the Bottom to the Top
Noyan Er, Dokuz Eylül University.Date: 13th of March, 2019, Wednesday. Time: 09:30-10:30Place: Dokuz Eylül Univ., Tınaztepe Campus, Faculty of Science, Department of Mathematics, Room B206.Abstract: After finishing up a leftover result from my last talk, we will discuss, as a natural follow-up, a characterization of Artinian principal ideal rings due to Eisenbud and Griffith the ...
