Title: A KLR-like presentation for the Hecke algebra of G(r,p,n) 

Abstract: The Hecke algebra of G(r,p,n) can be seen as the fixed point subalgebra of the
Hecke algebra of G(r,1,n) (also known as the Ariki-Koike algebra) for a certain
automorphism sigma.  Using an isomorphism of Brundan and Kleshchev with a KLR algebra, we
find an analogue of sigma defined from the KLR presentation.  Moreover, it turns out that
we can give a KLR-like presentation of the fixed point subalgebra.
