Title :  Total positivity in Springer fibres

Abstract : 

Let $u$ be a unipotent element in the totally positive part of a complex reductive group.  We consider the intersection of the Springer fibre at $u$ with the totally positive part of the flag manifold.  We show that this intersection has a natural cell decomposition which is part of the cell decomposition (Rietsch) of the totally positive flag manifold.
