CIMPA-UNESCO-TÜBİTAK Summer School 2008: Codes over Rings

August 18-29, 2008

Middle East Technical University, Ankara, Turkey Contents [hide]



Themes and Objectives

From the seminal work of Shannon of 1948 till the end of the 80's the algebraic framework of the theory of error correcting codes was within the confines of vector spaces over finite fields. Beginning in the early nineties a paradigm shift occurred , and modules over finite rings entered the armory of coding theorists from engineering applications like low correlation sequences to finite geometry and number theory . The aim of this school is to present a survey in fundamental areas, and to host a mini-conference highlighting some recent results. For detailed information please visit

You should tell the taxi driver that you will go to METU (ODTÜ in Turkish) and you will get off in the dormitories region. You don't need to give the explicit address of the METU campus to the driver since it is very well known. The taxi will probably be stopped at one of the gates of METU Campus. The security will ask the purpose of your visit. You should tell them that you came for CIMPA Summer School. We will inform the security beforehand and you will be let in.

Turkey operates on 220 volts, 50 Hz, with round-prong European-style plugs that fit into recessed wall sockets/points. Check your appliances before leaving home to see what you'll need to plug in when you travel in Turkey. Many appliances such as laptop computers and digital cameras with their own power adapters can be plugged into either 120-volt or 220-volt sockets/points and will adapt to the voltage automatically. But you will need a plug adaptor that can fit into the recessed wall socket/point. Read the technical stuff on your power adapter to see "INPUT: A.C. 100-240V". If it reads that way, it can operate on either 120 or 220 voltage. If it says something like "INPUT: 100-125V", then it can't run on Turkey 's 220 volts and you'll need to bring a voltage converter. Local time is equal to GMT + 2 hours. Same time zone all over the country (seven hours ahead of U.S. eastern standard time).
