### 16~17 Dec 2013: Dr. Hai Dinh from Kent State University USA

Algebra Resarch Group ITB and Combinatorial Mathematics Research Group ITB will organize “Lecture Series on Codes over Rings” with following details.

Speaker: Assoc Prof. Dr. Hai Dinh, Department of Mathematical Sciences, Kent State University USA

Time: 08.30 -12.00

Place: Mathematics Building Labtek III ITB

Abstract :

This series of lectures is devoted to giving an introduction to an area of applied algebra in coding theory. Foundational and theoretical aspects of algebraic coding theory are discussed with the concentration in the classes of cyclic and negacyclic codes over finite chain rings. The significant role of finite rings as alphabets in coding theory is presented. We overview results on both simple-root and repeated-root cases of such codes. Many directions in which the notions of cyclicity and negacyclicity have been generalized are also

considered.

We will also organize a Seminar on “Some Applications of Information Theory in Economics” which includes applications of information theory in gambling and economics (involving with stock market, portfolio theory, etc) with following details.

Date: Tuesday, 17 December 2013

Time: 15.30-16.30

Place: Mathematics Building Labtek III ITB
