Student Seminar: Bifurcations with Applications

by

Abstract: Last spring, we gave a presentation on chaos theory, where we discussed many concepts within the scope of the theory. In this presentation, we aim to explore the behavior of dynamical systems through examples drawn from everyday life. From changes in the Earth’s climate to predator–prey interactions observed in nature; from the operating principles of lasers to the extinction of languages spoken in the past, we examine these processes from a mathematical perspective. We would be pleased to have you join our presentation.

Origami Axioms and Constructible Numbers by Origami

by

Atakan Özcan and Pınar Ecem Akyıldırım, Dokuz Eylül University.
Date: 4th of December, 2025, Thursday, Time: 15.00 – 16.00.
Place: Dokuz Eylül Univ., Tınaztepe Campus, Faculty of Science, Department of Mathematics, Classroom B255.

Abstract: We will firstly mention straightedge-compass constructions and five axioms for them. By straightedge and compass constructions, we will talk about, drawing lines and circles, constructions of a perpendicular to a given line through a given point, drawing a parallel line to a given line passing through a given point and bisecting an angle. Then we will see basic properties of origami and the Huzita-Hatori seven postulates for origami. Another set of axioms for origami is obtained by just adding another axiom to the five axioms of straightedge-compass constructions. We will show the equivalence between these two sets of axioms for origami. Trisection of an angle is known to be impossible using straightedge and compass constructions, but we will see that it is possible using origami constructions.

Student Seminar: To Chaos and Beyond

Title: To Chaos and Beyond

Speakers: Şüheda Dilmaç, Naciye Çağlar

Abstract: In this student-to-student presentation, we explore the fascinating world of chaos theory
together! Concepts like the butterfly effect, the Lorenz attractor, and fractals are explained in a
clear and fun way through real-life examples and interactive content. A delightful introduction for
anyone curious about chaos!
