Title:
On divisible linear codes.

Abstract:
Divisible codes have been introduced by Harold Ward in 1981.
A linear code C is called Delta-divisible if the weight of all
codewords is divisible by Delta. Divisible codes are interesting for
various reasons, amongst others:

* Many good codes are divisible.
* (Hermitean) self-orthogonality of binary, ternary and quaternary
  codes can sometimes be generalized to divisibility.
* There are results and conjectures about the divisibility of
Griesmer-optimal linear codes.
* There are interconnections to other research areas like Galois
geometries and the theory of subspace codes.

In this talk, we will examine old and new results about divisible
linear codes. Moreover, applications in Galois geometries and subspace
codes will be discussed.
