Description
In this talk we will look at codes spanned by the rows of a quotient matrix of a symmetric (group) divisible design (SGDD) with the dual property. We will define an extended quotient matrix and see that under certain conditions the rows of the extended quotient matrix span a self-dual code with respect to a certain scalar product. We will also see that sometimes a chain of codes can be used to associate a self-dual code to a quotient matrix of a SGDD with the dual property.
Joint work with Dean Crnkovic and Sanja Rukavina.
