Tarih: 21.04.2022 (Perşembe) 10:30

Yer:B256 Nolu Derslik

Konuşmacı:Doç. Dr. Christian Lomp (University of Porto)

Özet: In the first part of this talk I will give a short introduction to the theory of Hopf algebras. After surveying basic examples of Hopf algebras, their actions on rings as well as their basic properties I will report on my recent joint work with Can Hatipoglu on finiteness conditions on the injective hull of simple modules over Noetherian Hopf algebras of finite Gelfand-Kirillov dimension.

Konuşmacı:Doç. Dr. Burcu Silindir Yantır

Özet:In 1729, Goldbach sent a letter to Bernoulli asking whether it is possible to extend the factorial function to nonnegative real arguements. The answer for this question was studied by Bernoulli and Euler. In this talk, we will present the journey to Gamma function and discuss its properties.

Two Theorems on the Fibonacci Numbers

Yer: SAKAI/Ogr DEU Math

Konuşmacı:Prof. Dr. Halil Oruç

Özet:We present two theorems about the Fibonacci numbers. Zeckhendorf’s theorem represents every integer uniquely as a sum of Fibonacci numbers. Lame’s theorem uses the Fibonacci numbers to determine complexity of the Euclidean algorithm.
