A geometric proof of Wedderburn's Theorem
at 3pm Friday 26 September in Weatherburn Lecture Theatre.
Abstract:
J. H. MaclaganWedderburn (1905) exploited the interplay between a finite division ring and its group of units to prove that a finite division ring is commutative (and hence a field). One of the most wellknown applications of this result is that a finite projective plane is Desarguesian if and only if it is Pappian. It is perhaps not as wellknown that Wedderburn's Theorem also implies the DandelinGalluci Theorem for finite projective 3spaces. In joint work with Tim Penttila, the DandelinGalluci Theorem plays the central role in a proof of Wedderburn's Theorem, thus completing Beniamino Segre's dream of developing a proof of Wedderburn's Theorem that is truly geometric.
