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.
