The sources and interpretation of Olympic Law
In this article, Mark James and Guy Osborn discuss how the relationships between the various members of the Olympic Movement are governed by the Olympic Charter and the legal framework within which an edition of the Olympic Games is organised.

Finally, by using the UK legislation that has been enacted to regulate advertising and trading at London 2012, the far-reaching and sometimes unexpected reach of Olympic Law is explored
On Hirzebruch invariants of elliptic fibrations
We compute all Hirzebruch invariants for , , and
elliptic fibrations of every dimension. A single generating series
is produced for each family of fibrations such that the coefficient
of encodes over a base of dimension , solely in terms
of invariants of the base of the fibration
